I’m having a bit of a hard time “seeing” what I’m looking at in his diagrams
You’ll need to double check, but he uses a technique in which he establishes rabbets and arrises to guide the rounds and hollows. Look at the six diagrams at the top of that page, the ones in light purple.
The three on the left show how the concave round is made. In the top left, a shallow, wide rabbet is cut (red). In the middle left, a square rabbet is added.This produces two arrises and a rabbet to guide a round which then removes the material in red in the middle, left diagram. The end result is the bottom left.
The three on the right show how the convex round is made. In the top right diagram, a shallow, wide rabbet is cut. In the middle right, a chamfer has been taken off. The red material in the middle right is what will be removed by the hollow, which is guided by the arrises of the chamfer. I suspect the bottom right was just supposed to be the purple part, (no red) and shows the final convex part of the joint.
I think that’s what is being shown. Hope that helps. His book might help.
