At the very least it's mashing them together in such a way that about 50% of the time they form anatomically correct humans. So at the very least it is rotating and shrinking limbs in a three dimensional way and internalized that. The other 50% of the time it goes wrong, and the result is either a human that is not anatomically correct, or something that doesn't even seem to be a two-dimensional projection of three-dimensional Euclidean space.
