I hope I am doing this correctly..I had finished Fallout 4 before the DLC and now again after the first DLC has been released...
Revised after DLC.....

If he decides to complete the dlc and repost his completion, it will almost assuredly lower both of your epic scores for that game (also a valid strategery for "catching up" to someone)
Under the original rules, if dlc came out, you would lose the completion, but that was far too difficult to track for so many game and gamers. Current rules state that you cannot lose a completion by having additional achievements come out. It's up to you and the others competing to determine if it is strategically advantageous to post a recompletion.
