Stopping in a lowered position is misleading, because you have to alter the technique substantially to stop. Many intermediate students try to control their timing in relation to the music by controlling their body speed when lowered, which is the natural extension of assuming you can stop there. The thing is you can't control your body speed when lowered without doing bad things, such as leaving your hips behind as to keep your balance over your foot longer. You have to control your body speed when lowered by controlling when you begin to lower, or better by controlling your rise such that it will come down when you want it to, and not before.
