Ah, yes, you're right.

It would make sense if it were intended to allow people to issue AUTHINFO
USER/PASS after successful AUTHINFO GENERIC and have it still work if they
use the same password (working around broken clients, maybe). But that's
no longer supported by the code. I suspect that we may have changed this
along the way and made the code dead.
I think you can take out PERMpass at this point.
