Hello,
On Simple English Wikipedia, people sometimes get notices that their edit was reverted, when in fact it wasn't.
Suppose an article with an Edit history:
*A .... article created
*... a few edits...
*B ... some editor makes a change.
... more changes..
*C another medtor makes a change
*D editor reverts the change to one version before C.

I think we all agree that when D reverts the edit o C (to C-1) or whatever, B shouldn't be notified.

It looks like that B in notified, in some cases, when D reverts the change of C...
