The AF tune value alters the camera's interpretation of what's in focus (phase detection).

To understand this better, first go to this page and play with the java applet to get a sense on how phase detection works by moving the "lens position" slider around.

Thanks for providing that link.  I've never seen that page.  Pretty cool!
