Well if I can throw my $0.02 in...From what your saying he may be sober but he's a "dry drunk", I say this from experience. Things you may want to ask, if you can, is how many meetings is he going to a week, does he have a sponsor, ect. The biggest thing about the process is him figuring out why he drank so much until then he's is a "dry drunk"...BTW the IC may help but rehab (out patient) would probably be a better option, IF he's serious about sobriety he will find a way to go.
