Zombies and similar creatures are “conceptually possible” when someone doesn’t understand the connection between lower and higher levels of organization, so that the stored propositions about the lower and higher levels of organization are mentally unconnected and can be switched on or off independently. This is a fact about the person’s state of mind, not a fact about the phenomenon in question.
I kind of see the point about logical possibility being what you get if you switch off your knowledge of how the world works, and just run off a minimal axiom set. But I don’t know what the connection between that particular set of lower and higher level of organisation is, ie the connection between consciousness and mind. I don’t think anyone else does. Zombies are logically conceivable for everybody. But conceivability is not about the world, as you say.
I think I can forgive it this once.
