I have a report from a user that [[commons:File:Chiesetta_a_Fénis_1.JPG]] and [[commons:File:Castello_Jocteau_5.JPG]] were actually two images each (for unknown reasons), but uploading a reverted (non-current) version under a new title failed, presumably being considered a reupload/duplicate by unauthorised user.
When I tried with the UW I got an unknown error in the first step but normal upload worked: [[commons:File:Chiesetta a Fénis 2.JPG]], [[commons:File:Castello_Jocteau_7.JPG]].
Note that reverting the file to the first version resulted in the first file in file history being lost: related to bug 39615 comment 5? Another byproduct of bug 39221?
In summary:
1) Upload two files A and B
2) Expect they are uploaded as files A and B
3) Find that A is uploaded as A, then B is uploaded with A's title (as a new version)
4) Try to upload A under a non-A title (or B with its own title after reverting A's title to A file)
5) Find that you can't upload the file, or history gets lost in the process, or both
