It really bugs me whenever I see this as evidence of AlphaGo playing in some fundamentally nonhuman way. It's a basic tenant of Go strategy that, if you are ahead in points, then you play conservatively. Professional players are very good at counting territory and assessing point values netted by various moves, especially in the endgame. They'll take a smaller margin and a safer win over a riskier but larger but riskier margin, too.
