To nullify limb leverage we need to get arms and legs as straight and as far from the torso as a scenario allows:
In the case of the legs this involves uncoiling the knees, as locked leg action effectively shuts down the pushing and pulling power of the hamstrings and quadriceps, making movement hip flexor dependent.
Likewise, getting an arm straight disengages the pushing and pulling power of the biceps and triceps, while moving the elbow away from the body isolates movement dependency to deltoid/shoulder muscle instead of the much stronger back/lat.
Thinking about this now, where the leg connects to the hip is similar to the ball and socket shoulder joint, albeit less range of motion.
Last but not least, this concept can be utilized from structural disadvantages illustrating that you can dominate from cross-sides bottom (this is where the point thing messes with people’s natural sensibility).
