Just a thought: could the AK be specific to the target? When Voldemort's wand got hit by the priori incantatem/brother wand effect, it actually summoned
the souls of the people he had killed, instead of just a ghostly form of the cast spells. This would seem to indicate that a casting of the AK is somehow
optimized or linked to the one it kills, enough so that the wand's "memory" of the spell is the actual soul of the victim.
