By analogy: the Lizard King of Russia does not exist; the Vampire Queen of New Orleans also does not exist. We don't therefore conclude that the Lizard King and the Vampire Queen are therefore the same person.
But it's equally invalid to say that they're not the same person, because it's meaningless to say anything about the properties of nonexistent people.
