Comparing chess and go AI to one another isn't a great comparison. As a high-level chess player, when a chess computer makes a recommendation to me, I can generally immediately recognize the reasoning behind the move, although I may need to investigate to understand why it's better than other options. Chess engines are recognizably different from human players in stylistic ways (no fear, etc) but the way in which a top tier engine like Stockfish plays chess "oddly" is very different from how AlphaGo plays go "oddly".

Stockfish views chess completely objectively, unlike a human, but ultimately plays in ways that a human can recognize immediately.

AlphaGo, apparently, does not.

This may change over time as human Go players learn from the AI.
