Good point, but I don't think it provides a good "teach" for kids 12 and under, which is the group that typically has this problem. By 13U kids who drag the bat are usually out of the game.
The "teach" for this I see is "keep your hands inside the ball" or "throw the knob of the bat toward" the pitcher, plus tee work on hand path, either two-handed or one hand at a time, with emphasis on the bottom hand. The "fence drill" is very simple and can be helpful too. It's more for casting, but that's a similar problem.
