Thanks a lot for the question at 1:03:00 - I came here to get the answer to this question (I didn't get the point, reading the paper). Now I have my answer.

Although, if the wheel is connected to the 4-chain (like drawn later on the slide), then at the edge connecting them, there will be a local rotation (change of the local angle) that I'd expect the L=1 models to capture. Am I right ?
