It's not lying if in his mind, one drink doesn't affect sobriety and it wasn't a "relapse". I guess that's the point, it's up to him to make that call and we're not in his head. Again, one drink would be the end of me, but apparently it wasn't for him, and perhaps it was something he needed to do. We also don't know his history, how far down the rabbit hole he went.
