I understand where he's coming from, although it is pretty annoying.
He teaches the language in the form correct for your country, it's pretty similar to when we're told how to correctly pronounce 'Z', 'Aluminium' or spell 'Colour' the right way. It's correct for the British, but not the Americans. I think it's fair enough that he would say that, it would hardly be ridiculous in the reverse situation.
Having said that, he sounds like a bloody wanker!
