I have believed that the jjverse was a separate universe before the excursions of Nero and Spock. This seem to evidencecthat it is the caze, coming from Orci.
From Trekmovie.com, shortly after the release of the 2009 movie:
GaryS: Was the timeline that Nero visited the original past up to the point that George Kirk is killed? Or was it always an alternate timeline because Nero was destined to travel there?
BobOrci: We think of it is as identical to the original until Nero arrives.
It's possible they've changed their minds since then...
