To answer your question on why 2 edits got reverted instead of just one, let me explain.

When you hit Rollback, the server reverts all the edits made by User X until the closest edit to the next unique user. To illustrate what I mean:

If the edit history goes like this:

X

X

Y

X

Then the two edits made by User X after User Y made the edit will be reverted. The edit made right before User Y edited will remain intact. To solve this problem, simply hit the Undo button and Publish instead of Rollback. :)
