haha, i just did a test.

extend right hip, right ankle

contract right pecs

left rotating chest, bending lumbar

p

check score. it should be 9431

do the same thing except reversed, change all lefts to rights and rights to lefts

check score. it should be 9439

have both uke and tori go limp, and their end positions are different... very strange

i would say its positioning, but: for tori, extend ankles, and raise shoulders, he falls perfectly symetrical... theoreticly if it were positioning, tori would not fall symmetrically
