And yeah, in the extras, Guerrier actually mentions that his early draft mentioned them having met the Sixth Doctor and Peri, but he took it out in order for the story to have a more authentic 60s feeling, and in a way to feel like a 60s story that "The Two Doctors" was actually later referring to in the 80s. But the intent is definitely still that "The Two Doctors" takes place within "The Black Hole". As I said, any discrepancies can be explained by the Doctor not remembering a meeting with his future selves.
