Can we safely assume that this is just a bunch of nonsense? If it were true, "Let's Kill Hitler" should have been the last time we ever saw River, since it was the very first time she met him.
We also know that River lies, but I have to assume that she wasn't lying when she foreshadowed "a worse day coming for her" at the beginning of Season 6. We know this to be when she meets Tennant in the Library.
Could it just be that, up until that point in her life, they had been living back to front? I keep picturing the scene at the end of "The Day of the Moon" when River kisses the Doctor for his first time (and she assumes it will be her last). I would absolutely love it if, immediately after the Doctor leaves in the TARDIS, a future TARDIS appears, and a future Doctor steps out and kisses her again, completely disproving the "back to front" idea.
It's simply an inconsistency that I'd like to be given a definitive explanation.
