Description:
Observations:

• Some of these are rollbacks, some are simple edits.
• Most are with the same user, but sometimes simultaneous rollbacks from two users are each being registered.
• Most seem to happen within a second or less, but longer delays have been seen, ~7 seconds +.
• Two in a row is most common. [[Neptune]] on en.wp shows an example of 4 in a row.

I was able to replicate by clicking rollback very fast, opening in new tabs:
