As a side note, I like to keep SWB in reference to a BO where a pressure differential occurs in the lungs, from surfacing from deeper water. But thats just semantics.

Its not semantics- its the definition of shallow water blackout. Of course if you black out on the bottom without trying to ascend, is still a blackout, and still likely to be fatal. Its just not the classic shallow water blackout in which the partial pressure of oxygen in the lungs becomes less than the partial pressure of oxygen in the bloodstream, causing a transfer from the bloodstream to the lungs.
And just in case its not clear, I think shallow water blackout is the biggest danger facing us, and I'm sure not trying to minimize it. My point was that this author didn't really know why the guy died, but just used his death to launch an article describing shallow water blackout.
If that helps increase awareness of the dangers of shallow water blackout, then that is a good thing. I was only objecting to the fact that many people seemed to confuse his article with a finding of the cause of this death.
