That's an interesting question about the effects of caffeine and soda during
a race.
I have not checked the literature, but a few of my patients who are
endurance athletes claim that there are benefits to using Coke or Pepsi late
in a race. I have personally used Pepsi in the final hour or so of an
Ironman, and I've seen great results. In my experience, the trick is to
drink small amounts at regular intervals, and once you start drinking it,
don't stop until the finish. The caffeine will transiently increase
glycogen breakdown, and give you a final boost of energy. The straight
glucose from the soda will enter your blood rapidly and give a rise in
energy for a while, until your insulin response kicks in (and then probably
overshoots) and brings your blood sugar back down.
I wouldn't be surprised if that's what the pro was doing at the end of the
Tour of Willamette, just getting an extra boost at the end of the race.
