This does two things. He can continue to drink (in moderation) under the guise that he'll be successful at drinking (in moderation) with your help and support, (so he doesn't have to give it up all together). In his mind it also deflects some of the responsibility from him to you.
Classic stuff. He's good.... Very good. You'll need to get up early in the morning to stay on top of his smoke and mirrors routine.
