I have never, and would never use the position shown in the photo, standing so far away from the fence, with virtually zero control of the workpiece. It would be ridiculous to place both hands together at that point shown. My right hand would be between the fence and the blade, with my thumb pushing the workpiece, rather close to the blade line, and possibly at least my pinky wrapped over the fence. My left hand would be in a similar position, but on the other side of the blade, pushing the offcut through (if the blade was through).
Only when I am trimming to size (when there is no offcut) do I use my left hand on the far side of the blade to insure the workpiece stays down and against the fence.
