How can I test to see if Occlusion target area is working?

After watching what some called a tutorial on Unity's occlusion culling I still have questions regarding the "target area." I created a "Visible area" but even if I uncheck the "Is target area" option it still creates blue boxes. I created another area called "Target Area" and checked the Is Target Area box (tried both unchecking and checking the Is Visble Area box), set up the target area where I wanted it and baked both areas (or can I just hit bake on one area and it will bake all of them?).

The moving object goes into the the target area but doesn't disappear. Any ideas?

It'd be great if a step-by-step video was released to go into a step-by-step example about some of the new features of Unity. The iPhone tutorial help clarify the visible area but it gets cut off when it goes to talk about the target area.

I didn't realize that the target area must have a "High" or greater resolution. I was using "Low" and thought nothing of it but I couldn't get an example to work with moving objects. After changing the target area's resolution, which by the way, didn't necessary take a huge amount of time longer to bake (unlike changing the visible resolution!) my demo worked great.
