I'm very fond of »inward-pointing guillemets«, personally.
We in Germany use the so called 99/66 style quotes. But in typography it’s also possible to use >>/<< style. But as a single font character. In the Field of layout the selection and usage of the right quote and space characters etc. is known as micro-typography. To know and being able to apply typography rules from different regions of the world must be an art form.
In Germany we like to use >>/<< sometimes and we call them Chevrons. In France and Switzerland they use <</>> and they call them Guillemets.
German quotation marks, so not really correct for English. And the backwards apostrophes I don’t think would even be correct in German?
According to Wikipedia, there are a lot of other languages that use that style, including countries that have much higher rates of fluency in English than Germany. If I had to guess, I'd guess that the author is dutch. https://en.wikipedia.org/wiki/Quotation_mark
The style of question marks used, while perhaps correct, is extremely uncommon in Dutch. It's also not easy to type, even with a Dutch keyboard layout. I'd bet that the author is German.
They depend on your locale/editor rather than keyboard. If you switch to Polish for example, Word will auto-correct the first quotation mark to the lower version. (Or did years ago) I've never had to type one explicitly.
The name of the "owner" of the Google Drive document is Dylan. Not sure if that's the original author though.
We would sometime use that in Norway too. Don't do myself, but feels more natural to keep both at top.
