And then he is connecting the resulting vertices with lines along the surface of the sphere. The lines look straight from head on, but are curved in 3d space.

Actually I think you use delaunay tetrahedrization on the points in 3-space. The points HAPPEN to be on the surface of the sphere.

Then you intersect the sphere with the polytopes, which result in great arcs.
