It goes with everything we have learned about Esper abilities in the series, also the fragment system is used in the same regard, throughout ZTD the player is constantly SHIFTing between the characters, being injected makes you forget what occured, but by the end of the game, the three protagonists are able to remember everything due to reasonance.
