Do the multiple, all-unreliable explanations for Sherlock's suicide in Sherlock count as this trope?
This trope should really be much more specific. As it's used right now, it almost seems like a supertrope of Continuity Snarl, Expansion Pack Past, and general insanity. That's a lot of overlap.
Multiple-Choice Past could be a meaningful trope - a character for whom inconsistency and uncertainty about their backstory is a significant part of their character - but people have added pretty much every character whose backstory has ever been retconned. The Joker, Black Beetle, and the janitor on Scrubs have Multiple Choice Pasts: no one except maybe the character knows what's true, and the writers want it that way. Power Girl, Sylar, and Warcraft's Thrall do not: at any one time they have had normal backstories, whether or not characters actually know what that backstory is, it's just that writers keep Retconning it or time travel stories result in a Cosmic Retcon.
So, thoughts? I'm not going to rewrite the intro and delete a third of the examples (rough estimate) by myself, don't worry, but I think this trope could be much better.

That's a project for the Trope Repair Shop— you'll probably not get much consensus here.
This has got to be like the 5,000th time I forgot my email or password...
There was one case in Big City Greens. Lampshaded by young Bill Green in a flashback.
Alice: How do you think I lost my leg?
Bill: I don't know, the story keeps changing!
