Wrong , you cant correct an out of focus planar subject taken with techniques that have spherical or cylindrical "planes of focus" after the fact with software.
The photo on that page neither has a near field planar subject nor a very wide "panning" angle looking at the subject. I don't see what lens he used or distance to far wall specified, is it described on another page?

I made the reference to macro lenses not Herb, I was being facetious. As you should well know virtually all 35mm format lenses excepting the best macro designs don't provide planar focus. Yes the panning effect will swamp the lens errors but there is software which can correct these aberrations (obviously only for image with an AOV of under 180 degrees).
