Yes, but they're essentially just scraping the surface of those types of moves. In chess it's similar — I'll happily trade down "losing" material to a won endgame. But humans do these things typically only when they can get to an ending where they're 95%+ sure they will win. AlphaGo will do this in any situation, from the beginning of the game all the way to the end.
