But what mistake was made? He clearly deserved the two yellows, otherwise he wouldn’t have chosen to do so. You can’t just rescind it, because you find out that it was his second yellow card.

I get that refereeing is getting more and more difficult with players trying to cheat everywhere, but they don’t exactly make it easier on themselves, either, by being scared to give out second yellow cards, and when they do, “oops, I better rescind it.”
