I know that there was only a few days period between when vin became preservation and the first preservation died, he could have become it and furthermore why would he give it up because its power could easily help him fulfill his goal, I am wondering this because on his page it says formerly preservation

Have you read Secret History?

Secret History, it fills in what happened from his perspective after he died.
