The problem lies not with the line of thinking. The problem lies in the continued refusal to consider anything which fails to conform to a narrow, preconceived notion of the Way Things Are (Star Trek version) that is not even consistent with all of the on-screen Trek which existed before this movie came along.

Because of that branching, he will not be able to count on history playing out in the same way as it had in the Prime timeline with which he is familiar. That's a parallel universe...
