Occam's Razor applies here. Simplest solution is that it's not our Spock. He came from another parallel universe, where he never had those time travel adventures (and thus no experience in resolving problems like this), and either time-traveled back along his own timeline, or was shifted into yet another alternate universe.
Really? I would think that Occam's Razor would say that the simplest solution is what the people who made
the movie intended (and what Leonard Nimoy himself would undoubtedly agree with): That this was the Spock from the TOS universe, not that convoluted mess you just wrote.
