Based on my understand of CFBundleTypeRole, it should definitely not autosave on top of the original file. Sounds like a bug to me too.

I don't have a solution for you, but I *thought* that NSDocumentController's new makeDocumentForURL:withContentsOfURL:ofType:error:, passing nil for the first parameter would have been a solution. It turns out that as soon as the document is closed, the original file is deleted. Not that it's documented *anywhere* that it does that. If it didn't delete the original contents url, this method would have been a perfect way to implement the behavior you want, and would have been good for my case as well. Le sigh.
