The example may not be doing the idea any service, but the idea itself seems to be to be able to peek at the content of a window without having to actually bring the window to the front. That said, i wonder if this is why some people love using "focus follows mouse" or whatever it is called. Just drag the mouse pointer to the window you want to peek at, then back to the main window once done. No need to look for safe place to click or use keyboard commands (though i guess something similar could be achieved with a WM that brings each window to front as you alt-tab around).
