Masks might be a question of anonymity in a semi-public context, but I think that some people wear them at home as well. Powerplay? Maybe, 'I establish my superiority by making it impossible for you to read my emotions.' Or 'I degrade you by putting a mask on you, taking away your individuality.'
I'm just guessing. I don't remember reading any explanations.
