Basically, they rev the engine and then release the clutch so the engine rpm matches the road-speed in the lower gear. It allows for faster release of the clutch.
Thanks I get that, and that’s a great breakdown but I’m thinking it’s that the brake is on the extreme right of the pedal box but maybe it’s just that unlike karts and modern F1 the brake is operated by the right foot, not that the pedal order is swapped or something. I guess driving a “normal” car this fact doesn’t seem odd but for a F1 driver it is.

I also found a nice article explaining the reasons and the technique: https://www.hpacademy.com/technical-articles/mastering-heel-and-toe/
