if you look at the 4 patch on the right, when cut 1 or 1 1/4" from the center on all 4 sides, then turn around the center piece 180 degrees that has the seams in it on all four sides, and resew it, I am assumming that because it has those extra seams now and looks faintly like a 9 patch at the left pics.
If you search for d4p, Jade has a great tutorial and there is another one that is done like this.
