I don't know that he offers "a smart anti-paleo" argument, per se, but Dr Ornish's program is highly divergent from Paleo when it comes to red meat, fat, animal sourced foods. He also includes grains, legumes and other non-Paleo foods in his program. His plan is very CW centered (calories in, calories out, and that red meat, saturated fat are evil), but does have some actual data backing it's success in heart disease reversal.
You can find loads of info on Ornish and his "Spectrum" program via the Google.
But all that said, a big part of his program is transitioning OFF the Standard American Diet processed foods, smoking cessation, meditation/relaxation techniques and the like. Undoubtedly those moves are beneficial and would be part of any Paleo Program as well! It's like the Ornish Program takes a half step from SAD towards Paleo, notes great results, and then vilifies the no-grain and acceptance of animal sourced foods that Paleo espouses. FacePalm!
Dunno that that is helpful to the original question, but I do think that the Paleo elements of Ornish's program are what makes it work.
