Its not working that way. Accuracy of your body movement depends on how many trailers are involved. In high sens, work of your wrist is depends on wirst trailers of forearm, while when you play on low sens, your wrist also works but there is a elbow trailer involved. If we talking about the sens, you are right but keep in mind we talk about sensitivity in game, which means your wrist movement is scaled. The less your move is scaled the more accurate it is, which means, ALWAYS lower sens will be more accurate :) You talking about the motion as it is, i talk about the motion moved in to the screen which is difference.
