What I'm really curious about is why he took it off mid-flight. Obviously it's a latex costume and a long flight, probably extremely uncomfortable but think about it, how is the person in the seat next to him not going to notice?

Given the refugee claim, it might have a lot to do with the fact he wanted to make no false claim on entry. Also the reaction of a passenger is likely to be more acceptable than if you attempt this at the airport and get noticed.

I'd really like to hear what caused this stunt, though.
