Are you quite sure? The direct quote given in the thread in question certainly seems to be written from an in-universe point of view. "The parallel world from which the Cybermen came was possibly split from our own when an event took place on that world but not ours: the death of Queen Victoria, killed by a Werewolf. This event was averted on our own world by the intervention of an alien wanderer in time and space — the Doctor."

It's probably another case of a book which contains BTS articles and fiction, not unlike, well, an issue of DWM.
