White may plan to push the g-pawn to g4 and drive the black bishop to g6 aiming to exchange his knight for the bishop later, playing the knight to h4. Thus 10...h6 gives black refuge. Besides, the bishop positioned at h7 would be very useful later on, perhaps after the push you mentioned that Zappa plays right away, exerting pressure on the e4 square... Just an idea. One glance at the diagram... Caveat emptor :-)
