That's not quite true. Again, using the Green mode example, the camera will sometimes pick more than one focus point at the same time and average between them. You can see the multiple focus points flashing in the viewfinder when this happens. The same is true if you have the focus point selector set to "auto", which is a setting I particularly despise.
But *I* never use Green mode! I just tried it out to see what kind of results it gave.
