As much as I realize that page is all about destroying a knife, I kind of like seeing the things that make them fail or otherwise become damaged. If you are going to be rough on it, then knowing it's limits can be useful. It's not going to become the standard by which I evaluate all knives.
Also, I'm not going to do those things with a knife, but I did remember the tests on the Kabar before banging mine into tree last weekend.
