Yes, this was clearly written by a film geek for film geeks. I had to google "dutch angle" for example. It just means you tilt the camera a little. But I'll see if I notice any of those things the next time I watch something.
I think the example image at the top of the article does a perfectly fine job of showing the "something" they're refering to, but it's only going to help those few who have already noticed that something, and haven't put their finger on what it actualy is. For readers who haven't noticed the effect, a few comparison images wouldn't hurt.
I don't have links unfortunately.
I think it‘s an AI generated text: a lot of filler words, no clear message and restates again and again a basic concept.
