My guess is that Starlight's temporal intervention was beginning to have effects up- as well as down-stream of the time-line as time tried to iron out the paradox she'd created. The last few alternate time-lines were due to changes that occured before the first Rainboom - One where Nightmare Moon won the Nightmare War, one where Tirek won his struggle with Star Swirl and ended up a power-maddened force of chaos just destroying everything in his path in a never-ending psychotic episode, one where Discord emerged triumphant and, finally...

... and finally...

Finally, one where something happened long ago, destroying all life in the land that would never become known as 'Equestria', because no-one would ever live to give it that name or any other.

If you try to push time, time pushes back.
