It's more dangerous than the normal way. The #1 most important part of using an ax is retaining full control over it. How is a kid going to have control of a 3' wooden pole with a 20lb log on the end of it? They certainly aren't going to be able to stop that axe if the wood falls off and the physics change suddenly. That's a horrible idea.
Then again, I have... issues... with the Boy Scouts in general.
