It would make a lot of sense for me to read it before just blindly posting something, so yes I did read it... but I really didn't have to since I actually KNOW how the thing works. You'll notice in my last post that I agreed to it having 4 fixed gear ratios.
To understand how it works you must know how a planetary gearset works. Since it is very difficult to explain in typed words, I will let howstuffworks.com explain it. The example they use is a prius but the two mode works in a very similar fashion.

When accelerating in a tahoe hybrid it performs very similarly to a traditional cvt (it hits about 4.5-5k rpms and just sits there as you continue to accelerate).

I hope you don't actually think that the transmission in this thing is an off the shelf 4-speed that GM just had lying around.
