It's similar to the difference between a practice engine failure (where you pretend you're going to make the field, and the instructor pretends to believe you), and a real one. Having suffered three, I can confirm there is a difference!
Similarly, real IFR, with no-one next to you to drop the occasional hint, is a world away from the foggles.
There is no excuse for that video, or any others of a similar nature.
