Maybe that's why the bike was on E-bay.
So, if I understand you correctly the drive side cup was right-hand threaded and the non-drive side was left-hand threaded. They are English dimensioned threads right? I guess someone used the wrong tap on the wrong side. Actually both cups should have unthreaded with riding.
If that's the case, Lock-tite is your friend.
