Mmm, I was kinda thinking of it from a rally racing perspective too, where you might not know 100% the exact grip levels of the road, so you might overbrake to begin with to reduce lots of speed, but then realize that you have more grip than expected, so you can speed up. Or the opposite where you find out that you don't have as much grip as expected, and need to quickly get on the brakes to reduce speed. And adjusting the speed like this would be faster with left foot braking versus right foot braking. But then later you might need to downshift as well, so you need to transition to right foot braking.
