But, I simply wasn't in the mood to type when I posted the link. That being said, the author of the paper was not addressing the issues of "non-radiative" electronic transitions which were left unaddressed by the original paper. But rather was addressing the issue of why the Klein-Gordon solution was not square integrable in the Dirac solution. Unless of course I missed the point in all the hand waving.
