I'm afraid you might be misunderstanding the meaning of this option and expecting something else. Painting first image on desktop means that the transition starts from the desktop instead of showing the first image at once.
It is NOT a new/different transition effect, it is a transition between what your desktop image to your first screensaver image using the transition effects of screensaver which you can customize by the way.
I did try your airport screensaver and the first image IS painted on / over desktop just fine which means you can see the desktop while the first image is being painted.
