You are right. I am sorry I mis-spoke. What I meant was that if the light moves a bit, the torque increases on the standing light, whereas it decreases on the hanging light. So in one case, you have a light that is balanced on a ridge, in the other, it's in a valley, so to speak. The main advantage of the hanging light is its ease of mounting on racks, as the originally-discussed blug post pointed out...
