Edit: ^^ ahhh that makes a little more sense. Thinking of a fast up-shift you'll be dropping two thousand rpm but the fan will be coasting in the mean-time. You won't have to bring it down 2000rpm and you might have a few hundred rpm to accelerate through before the fan comes back down to the matching speed. Interesting--curious to see how much impact it has.

Only time I can think that this would be a help would be during cold start warm up. Limiting airflow over the engine to only that needed to prevent hot-spots, but not really providing too much cooling.

Track days in cool weather are always a pain because of how long it takes to get the engine warm.

So in that case maybe...is this what they're going for?
