Comment 4 for bug 1493186

I think the issue is as Ricardo described, and I also think we should review the text from the transition emails.

On the other hand, if there were previous uploaded versions without a final review decision (which seems to be the case), since some time ago, on uploading a new one will automatically reject those previous uploads. This should have been a one-time thing only, being the first upload since that auto-reject previous got deployed. From now on, you shouldn't have more than one review pending version at a time.
