Creating an impression of language fluency out of a very limited set of words and phrases is a talent in its own right.
It certainly has an element of deception to it :) but he can still be legit in the sense that you mean.
Polish pronunciation is notoriously difficult, but once you can make yourself understood, pronunciation is of secondary importance. There's a lot of people with a near-native command of foreign language with accent as thick as mud.
I think that's the real difference maker for Tim's guest blogger, he has a strong sense of what a language is in the abstract, a sense for how people use language in general, and practice at getting through the awkward time when you are frustrating to speak with.
Those universal gifts are the most valuable ones of language learning, and they can come while learning your second language, but they come faster when you have dabbled in 4 or so.
Benny & Tim make some claims and use words like "learn" and "know" differently than you or me. I agree with you and don't agree with much of their preamble copy, but what they're doing is long held in aggressive training scenarios (foreign service postings, for instance) and a solid hack.. well, for type-A extroverts willing to dominate a foreigner socially.
What I think happens on the video is that the guy has a list of different phrases/words (prepared for this particular situation) and maybe some pronunciation notes. That's ok, I would do exactly the same. You just cannot memorize all the necessary core words in one hour but you can use them easily if you have a reference material (plus you keep the conversation going and practice more).
He does standard mispronunciations that every non-native Polish speaker does at the beginning. However, you can hear that when the lady replies in Polish, there is nothing to indicate that he actually understood what she said. He gets the questions after she gives him some hints in English. If he was preparing just for an hour for this skype call it is certainly an excellent starting point.
Agreed on that second part. I'm skeptical too but having seen Benny's Youtube videos and knowing that he already speaks a dozen or more languages and that he has reportedly learnt them enough to be conversational in months ... I think he has a handle on how to make specific sounds already and probably knows a lot of cognates.

He's not just a random guy, he appears to be trying very hard; I wouldn't call it fake without further evidence; he clearly has a great talent and many people appear to have had success using his methods (which he passes on for free).
In this TEDx video, https://www.youtube.com/watch?v=HZqUeWshwMs, he says he started learning new languages at 21. He looks mid- to late-30s to me which tends to support his "3 months" claim as being viable as well.

Pronunciation specifically can be hard to learn without actually focusing on it, such as recording your own voice or having a tutor specifically teach you how to make each sound. A normal class setting is very bad for learning pronunciation while a one on one conversation with a teacher focusing on pronunciation will bring much better results.
Anyway my point is, that you are able to pick up CoffeeScript in one hour if you are fluent in javascript and python, aren't you?
How many of them really have the incentive to be efficient? Maybe as long as the students are learning something, that is enough. I can't imagine that a large swath of Germans are going to form a protest ten years after graduation and proclaim that "my subpar Italian ruined my life", or something like that. English has been very useful for me, but I feel like I've learned most of it from the Web, video games, movies, other pop culture ... it's hard to tell how important it was at this point, though.
Most teaching is variations on "throw information at your senses until something sticks", and the input is reading, doing exercises, discussing. There's nothing about specific mnemonic techniques, just read it and hope that you recall it. In elementary school, they told us to remember 50 English words by trying to write them down and reading them, reading them and then trying to recall them, rinse and repeat. This technique is laughably inefficient compared to trying to associate the words with something, like associating things that the word sounds like or remind you of, perhaps in your own language.
