With remaining stack sizes as they are, maybe he thinks you would fold if he then reraises you all in. For this to work, you have to bet a little less than half the effective stack sizes, I think, so that his all in at this stage in the hand would instill fear in you.

It would only be a semi-bluff for him anyway, as he apparently has a decent hand based on his turn call. If he doesn't want to gamble, he might still call your small river bet. If he folds, he would have obviously folded to your all in.
