It's called late braking. You'll find out what it is if you autocross. I do it all the time which is how you become faster and one with your car. Knowing the limits of your brakes and tires.

I know if I wait even a 1/2 second longer in my car my tires/brakes will lock up and you just go straight. But I don't and I brake just in time for the corners without going into the grass or off course.
