"Reverts never cause an edit conflict - if between you pressing edit, and then pressing post, someone else edits the page, their edits will be silently overwritten (though still in the page history). Beware of reverting high-traffic pages! Conversely, if it looks like someone has deleted your edits, consider if it's more likely that it's one of these unfortunate reversion conflicts."
Clarification: that it text from the URL. I haven't tested this myself.
yes it is known that editing an old version WILL NOT create an edit conflict this is by design this should be in the help pages but it doesn't belong here
Why is this by design?
