This isn't really correct. There's four things you have to be aware of when going through a corner--throttle, brake, orientation, and traction. Oftentimes the fastest route through a corner doesn't match the bang-bang approach you describe. A good example is a series of chicanes where the bang-bang approach would actually make you slower. To put it another way, traction factors a lot more heavily into the best route around a corner and therefore demands fewer instances of full-on/full-off throttle and braking that you describe.
