[Two things happen next in rapid succession. The first is that any marks from Astarion's fangs that would have been opened and allow blood to drain out close without missing a beat. There were never fangs there, the only issue is the blood running down in little rivulets from the fleeting moment that teeth left flesh and Alucard's body had to react to the puncture.
The second is that Alucard absolutely falls back onto the bed itself, first light headed and then just out entirely, having miscalculated exactly how fast a hungry vampire might drain blood. There is no time for him to even consider if the experiment has been effective, he's just sprawled out and looking nearly as pale as Astarion, rather than his half-dead skin tone.]
