I made this rollback of an edit by Cort Ammon, where he removed an (in my eyes) good example that was a way to verify one has understood him correctly in what he was saying. At least another user stated in a comment he was thinking so too.
So I thought it would be a loss to remove that example.
But the reviewers of my edit a) didn't carefully enough check the overall case as they identified my edit just as beeing a comment to the question or a seperate answer (which definitely is not the case).
Or b) I simply missed something about this SE site, where it was not good behaviour of myself to roll back his edit.
So what exactly went wrong in this case?
