One or two drinks has been shown to have a positive effect on testosterone. So, it would seem logical to think that after the workout you might get some benefit from the higher T. But, the next morning you may have an unusually low T-level due to the alcohol. So, be sure and use some ZMA and maybe Alpha Male or other T-support supplement -- not that it will totally offset the damage but may minimize it and aid faster T-recovery.
Also, the alcohol is inefficient calories, so consuming after some activity may have your furnace burning more effectively and the alcohol may not do as much calorie damage. Generally, on days that I don't work out I try to make an extra effort to eat clean since the activity level is lower.
This is all pure speculation on my part, just trying to think through it logically. Obviously if you're going to get shit-faced drunk it doesn't matter -- it's pure damage regardless of timing.
