Indeed, but there are evidently some jointed/ligatured/pinned figures because there are some jointed movements. Stop-frame, obviously.

In some scenes parts of a figure simply do not move or change shape at all while other parts of the limbs do, and the limbs move in angular rotations before being swapped out for recut or different limbs. In the absence of machine cutting, the only explanation is that the figures are composed of pieces.

I am quite sure some jointing and "composition" of figures was used — not just for efficiency but for quality frame to frame.

It is absolutely amazing art but the level of craft is of the scale!

Just from the level of consistency even if you assume that film frames have been carefully realigned in digitisation.
