Word of God (Bob Orci over at Trekmovie.com) says it's a branching timeline beginning in 2233, that it's one shared history up until that point.
Ah, right. It's a single timeline time travel set-up with a multiple timeline set-up.
In this case, it would seem that there is, at least, a vague causal connection with TNG via Enterprise, since Enterprise was a single timeline story which shot through the entire history of Trek up through the Enterprise J.
