Very rare you say?.......... maybe I should buy a Lottery Ticket this weekend

Yes, you should buy a ticket.

The circumstance that happened to you, doesn't happen often enough for you to waste your time looking for it. (Same WU completed without errors twice.)
There are some circumstances where it might happen, though.
1) If you try to move work from one machine to another, you can cause duplicate assignments.
2) If the client finds an error (EUE) and deletes the work, it may move on to a duplicate copy of that WU. If you use one of several methods to un-delete the WU, you can get partial credit for the incomplete WU and then perhaps NOT get credit for successfully completing it later.
Both of these situations happen because you actively try to override FAH's choices, though. The unlikely situation is that it would happen without you doing anything.
