Sounds like a very dumb and convoluted way to change things and not call it a reboot but using time travel as an excuse to change things.
If the timeline is reset by Older spock at the end of the movie and none of this stuff really happened then they have wasted 2 hours of your time for nothing and you deserve your 10 dollars back followed by getting an apology from JJ and him never being allowed to direct a movie again.
