I do believe it is an effect of perspective. He isn't taking a step - his legs are even and facing us directly. However, his upper body is twisting at the torso - his abs are not facing us directly. Look at them closely - they are not vertically aligned, showing a slant to his left. Similarly, you can see this in the jacket being pulled forward on his right, coming just to the divide between his abs and pecs on that side while dragged back to reveal a little more on his left. You can also see, as another top level comment states, that the left shoulder appears higher from the twist. The right arm is then swung forward on top of this twist, and the left swung back - giving the appearance that his right arm is larger and his left smaller.
