There's no guarantee that even if he played in the NHL that he'd stay in NA. I think there's a perception by North Americans that everyone else in the world wants to be here. If he can play at home, still make a good living, play a lot less games, in a much less physical environment, why not?
I think that's the perception because he has already come to North America and is willing to play in a league here that's inferior to the NHL. If he really did want to play back home, I'd think he'd never have come over.
