The top is just slightly thinner, and a little thicker immediately under the bar.

I think Arnold means that if the platform is at a right angle 90 degrees with the Bar directly under it, sitting on it, it acts as a pressure point along the edges or the 'bar joint. I think that is what he is referring to rather than a gentle sloped platform in which the 'bar would sit. That's how the Gilkes is done. You can feel it but you can't see it that easily. It is slight but it is there.
