This is not necessarily what anyone would do for a real world photo. As stated, the compression / quality slider was biased towards compression. If you are saving changes biased towards quality, it would take a lot more saves to make a noticeable difference in the image.
If you are taking a small web image, and making changes to it, you might notice these effects after saving.

So, maybe this is the 1% I refer to ?

Simple, because people do that inadvertantly. l

The point is, why do something that might cause a loss if there's no reason to do it.

Why would you open and save if you didn't make any changes?
Some folks might think that they can make another "good copy" of an open image by saving it in a different location or under a different filename. However, this will invoke another JPEG compression cycle on the open file. The correct way to make a copy is to use the OS-level Copy/Paste commands before opening the image.
