In my quick, highly unscientific experiment, all my weight was on my right knee, so much so that I got up and got a pillow to put on the floor to try it again, cuz it hurt. jmoI can't judge where DC weight would have been based on the one photo.
What I can say is when I duplicate the position in the photo my weight is on my right leg, I can't apply weight to my left leg and keep my foot sidewise without pain or turning my foot to a toe to pavement position.
Just try it, its much harder than it looks in the photo, to apply any pressure to the left leg with the ankle turned. Yes, if I keep my ankle straight I can apply full pressure, no problem.
