The point is, he didn't see it coming so he didn't aim his hand at it anymore. Absorbing jutsu is an active effect, if Momoshiki's not gonna activate it he's not gonna absorb ninjutsu. and since he thought the technique simply failed, he didn't bother absorbing it.

If you activate the Blocking Absorbtion seal and just wait, any ninjutsu hit will be absorbed.
