I think it's used mostly to nudge someone out of the way that has gotten too close. Yeah the hand and shoulder stay pretty much where they are and your elbow comes up to give someone a bit of a push. I've never seen anyone lead anyone around the court with it or trap someone but I guess it could happen. It's very useful for pushing someone over the ball so you can take it from them.

Put your hands out in front of you as if they were on imaginary hanldebars. Now, take the elbow of what would be your mallet hand and stick it up and out. Move that elbow up and down. It looks like a chicken wing, no?
Now, stick that chicken wing up in someone's armpit and guide them around the court. Or pin someone's arm down with it. Or just use it to poke people.
