to add to this, the primary reason for betting that flop is to protect against the flush draw. but you don't have to do that here because of the reraise preflop, which is totally inconsistent with any possible two heart that the might have.

my mantra on AK is as follows: AK can only make you money by extracting value from weaker aces/kings or by inducing a bluff from a smaller pair when you hit. betting this flop reduces the effectiveness of both of those lines since you are advertising a strong A, which will slow down a weaker ace and will possibly get a QQ or KK to fold.
