Well, I'd actually label directly saying that those stories were erased as barely speculation. It's not directly explained in the episode, and I'm sure that Moffat would like us to forget about it even if it was him doing his best to explain some universal inconsistencies.

Better examples of the issue at hand are Journey to the Centre of the TARDIS, The Light at the End, and others.
