Screwing the layers together don't do anything except add mass at the bottom. The clamps afford a certain degree of resonance tunability on the plinth, especially if done at the corners. They look silly, but as far as I can tell, the whole ensemble works well in the context of the system. That's important – in the context of the system. I had a much heavier lead-loaded solid teak plinth for comparison which didn't appeal to me sonically as much and I got rid of it.
The small American walnut tonearm board is similarly clamped at one point and 2 shallow screws are deployed on the opposite side to keep the board in place. The tunability has a marginally greater effect here. That's not hard to envision, I think.
