You're saying the rim cannot cool when the brake is on?
No sure where you got this idea from. The rim is dissipating heat all the time, whether you are applying the brakes or not. When you use the pulsing technique all you're doing is increasing the average speed so the wind does more of the work instead of the brakes.
You can ride down the entire descent with your brakes lightly dragging. As long as you maintain the same high average speed as the pulsing technique, your rims will be fine.
Anyway we are arguing over semantics. Realistically, you're going to brake more at the corners.
