Although I have no idea about this, and, I am a bit skeptical, there seem to be many things that work that I had not expected. As examples, banging on saws with hammers to relieve internal stress and freezing metal (tools, gun barrels, etc). I believe that they statement was that he dropped large pieces, not sure if it makes a difference. I would like to see more on this before I would be inclined to try it. At least he does it up front so that any damage done to the wood is milled out.
Just because one person does it and believes it to be so does not make it so, and just because I don't believe it does not make it false. I watched a wood working show on TV where they were advocating dowsing. I believe that dowsing has never shown any results better than chance based on any study (I am only aware of two studies), but I know people that believe it to work, even one person in particular who has had more failures with it than success.
When I have a particularly tough piece of wood, I send it to a shrink first! It never helps, but at least the wood feels better about itself.
