Many times different host sites can vary when a player goes on the DL. I always defer to when the host site does it, it can suck sometimes when youre waiting to make a switch, pickup, or any other reflecting roster move but everyone's under it.
If your league wants to tweak a rule around that, that's great but frankly I think it would be a HUGE PITA sometimes if the move is really delayed.
