White's drawing back at leaves a big continuation at a. We can expect
to be sente and that Black will answer
at b, leaving more endgame for White at c

is a mistake here. The hane at a doesn't work anymore because White has taken away one of her own liberties:
Things are a little different if there is no black stone at a. White can play at a to make nice shape but it has to be bigger than the hanes at b. The deeper in the endgame, the less likely that will be the case.
