No, I understand that, MBM. What I'm trying to figure out is why these don't count, in OS25's mind, as alternate realities. Doomsday tells us that "every single decision we make creates a parallel existence, a different dimension". The fact that some of these decisions might get a "redo" doesn't obviate the creation of a parallel existence. The events of Last of the Time Lords "count" for the individuals who lived through "The Year That Never Was", even if they're not remembered by the vast majority of humanity.

Unless I'm missing something pretty major, I really don't see that there are different levels of alternativeness. There's the main timeline, and then there are the alternatives.

I think the distinction between Time & Time Again and The Light at the End is a completely arbitrary one. An alternate timeline is an alternate timeline. Neither how you got into it or out of it matters. What matters is only that it got created.
