When you step forward on your right foot, your whole body doesn't rotate with it.
Try it.
Did you step? You body didn't go through all the trouble of roatating with it did it? If it did, then you must've waddled.
Ok, now go for a little jog around the room.
Go on now.
See how when you step your torso doesn't really rotate with them? Infact, it should rotate opposite of them. It's when you swing your arms that your torso moves side to side. It moves side to side with the arms, not the legs. And if you'll notice, arms and legs move opposite of each other. Therefore one must conclude that the torso moves opposite the legs.
Like in Rox's edit.
In yours, see how the arm is forward but the rest of that side of the body is back, in conjunction with the leg's position? Well, yeah, it should be opposite.

That's what everyone's been saying.
I hope you understand.
