I don't fly in that part of the world but there are certain places I go that if you question something with the controller you'll get a really pissed off "Yes there IS a reason I'm doing it this way believe it or not" sort of reply. If that video exchange happened to me in one of those places I would be a lot more likely to not question the instruction than I would be in other more civil places where I have questioned something and actually had the ATCO say "No thats the way I need you to go for xyz but thanks for checking".
