Star Trek doenst make mistakes like that. They carefully duplicated the appearance of Spocks death in the wrath of khan to try to match his 'death' in the simulator at the start of the movie to trick people. You could have credits at the start of hte movie and I bet if osmeone like Kirk made an appearance his name wouldnt appear until the end credits.
EDIT: Spose I should say they used to be careful not to make mistakes like that, these days I guess I'm not as confident...
