Difference between Group AF and Dynamic 9-point AF?

What is the functionality difference between the D4S' Group AF focus mode compared to the Dynamic 9-point AF-C setting? I'm not fully understanding how the Group AF differs from the Dynamic AF. I thought in 9 point the AF point would move around on the outer edge of the focus point based on the subject's movement?

According to my tests, Group AF tends to pick the point at which the subject is closer towards the camera, while 9-point AF tends to pick the center point out of the 9.
