Well yes, but I was thinking more about validating that you are running the "How to reproduce" procedure correctly (especially for those of us who have not tried reproducing the bug yet). If you run the procedure on a known bad drive, and you can't make it fail, then you know something is wrong with the way you're doing it, or there's something odd about your system configuration, etc.. If your test is faulty, then you can't reliably tell if a drive has been updated or not.
I couldn't help but laugh at what an utter facepalm it would be if pre-firmware update you couldn't get it to fail, then post-update you couldn't get it to pass...
In that case, I think I'd rather not know it was passing beforehand...
