No, it doesn't. I tested the plugin and it only compresses the images which are bigger than the established pixels limits. So, if a user "not so lay" decide to do the right thing, uploading a previously reduced image, in terms of pixel, the result is worse than if he didn't do anything: the plugin simply will not compress this semi-optimized image.

So, if you want to use this plugin, you must always upload very big image files to your site. Don't dare to implement good practices of image upload: the result, as explained before, will be worse than if you decide to adopt bad practices all the time.

This is bizarre, but is the way the developer think the plugin should work (so far). I hope someday someone succeeds to persuade him to change his mind.
