One of the devs at Ubi said that they use the AC wiki to look back on past story events
I can totally believe it.
One of the main people in charge of the game admitted last year at a conference that they have no clue what they are doing with the modern day and only include it out of obligation.
At one point, it was one of the biggest storylines and mysteries in gaming and they fukked it up. I remember being pissed when I saw the ending for 3 lol.
