You can't "change his story". You can edit some parts out, but they still work within actual genetic memories. That's their gimmick, instead of creating actual new games, they just edit the memories of people into an interactive format.

Just like they did with Aveline - they could censor the shit out of her memories, but they still happened. Abstergo didn't go "take this girl and fabricate her entire life."
