It's entirely possible that he was just referring to the whole Everwhen thing. Now that Wash has been shot and we didn't have the reality-breaking paradox take place, that part definitely didn't happen and history is just as we remember it.

Jury's still out on the rest of it, though, because yeah, a lot of the time travel shenanigans explained more than a few defining events in the series, and the whole "Chrovos is Genkins" twist (which was absolutely brilliant, by the way) still requires the events outside of the Everwhen to exist in some capacity.
