No actual pic but imagine the 'support' sitting slightly lower than the stock location and everything moves down slightly. All the pivot/rocker wheels of the intermediate rocker are nearly in the same position and the foot on the primary rocker arm is in the same location, just pushed lower. In the picture, the intermediate rocker will be slightly lower at 80+% - WOT. The 'support' has a 'ramp' on the surface that the intermediate rocker roller rides on and pushes the intermediate rocker down at about 70%-WOT. It is that 'ramp' and the shape of the 'foot' that gives the ratio multiplication. This picture is at idle position, at WOT the eccentric cam pushes the intermediate top roller forward.
I hope that helps explain.
