I'll never use it, but I still find the physics of this method interesting. On one hand, beginners often need some sort of method, and on the other, it's neat to imagine the forces you are building while packing the tobacco. I never really thought about it, but the forces must be down and sideways, and this method actually considers that.
I think the easiest way to teach pipe packing is to explain the result, rather than the technique. You want the pressure even, top to bottom, but remember that the bottom gets tighter as you pack.
I think anyone with a functioning cerebellum can figure that out in whatever way by feel.
