Nothing. If Voldemort teleports or flies farther away from Slenderman and the latter closes the gap between them again with his own teleport, Voldemort will be able to once again apparate or fly to a different position before Slenderman has a chance to do anything to him. It is unlikely that the battle would transpire in this merry-go-round for very long, in which case Slenderman would stop persuing and try to fall back to his ranged abilities, only to find they aren't much use, and then be done away with by Voldemort.
