Am I degrading jpegs in Preview?

Hi. If I edit a jpeg in Preview and then undo the changes before closing it, the document still shows as recently edited in the Finder. Does that mean it has actually overwritten the file?? This is a lossy format and I do not want this to happen if all I am doing is experimenting with possible changes.

MacBook Pro, Mac OS X (10.7.5)
