Now you go to the Haptonomic explanation, I'll give you a scientific link which debunks at least part of the claim in your article.
Law RYW and Herbert RD(2007) Warm-up reduces delayed-onset muscle soreness but cool-down does not: a randomised controlled trial. The Australian Journal of Physiotherapy 53: 91–95
Now we can go back and forth, but this marginal gain seems to be rather marginal wouldn't you agree?
Both the physical warm down and the psychological warm down can be effected by a good masseur - where good does not just include someone who knows the insertions and your niggly bits, but also how to talk to you and talk you down from a tough day in the office.
It's my belief that both physical and psychological post-stage cool downs are required for peak performance, and that the massage fulfills that role as equally well as sitting on a trainer.
IMO (entirely non-scientific and decidedly amateur opinion) the trainer cool down offers no advantage whatsoever (over the traditional post-stage massage).
It's definitely more visible, however, and if anything, with all those people staring at you and waving syringes at you, it could potentially be more stressful.
eg: I personally think Popovich is weak, but even having someone for whom I have no respect laughing at me, would have some form of negative influence on the riders / team (imo).
