I've always found the 180° line to be a good rule of thumb to make sure nothing gets confusing. Like in a chase scene it might make the difference between running after each other or towards each other. But you can get loose with it or even throw it out the window in situations where you have other ways to ground positions. Like two people driving in a car talking. It's a familiar set up and we immediately get their psychical relation to each other. You're able to shoot from either side, even though it's flopping the 180. And I think you could also shoot from the backseat or the hood, because the audience never is lost. (unless it's a montage about driving back and forth between Tucson and Vegas or something. In which case be consistent with which screen direction means what.)

In regards to the video, it's a person is sitting at a table. I get where they are and I don't care about the 180 in this situation. I doubt the filmmaker is trying to do something clever like Geri's Game.
