Exactly! I’ve been pointing this out too. If you assume preference utilitarianism, then killing counts as wrong, at least if the beings you kill want to stay alive further (or have detailed future plans even). So the replecement only works if you increase the number of the new beings, or make them have more satisfied preferences. The rest of the argument still works, but this is important to point out.
