Does confluence allow for creating an empty diff? Why?

When changing confluence pages, it seems that you can create an empty (no-op) change to a page, which is confusing to me. Is it truly an empty change, or are there things that the diff isn't able to show? Why does it allow you to do this? Is there a way to prevent this from happening?

@Ben Johnson You are correct that you are able to edit the page, make no changes and save it creating a no-change version.  There is no way to prevent this as Confluence does not check on each save if any changes have been made.
