Well, it has a couple of purposes. The only time I heel/toe is when I'm accelerating from a stop on hills. Others use it for rev-matching during downshifts, particularly in corners. That's why you see it referred to as heel/toe shifting many times. Still others use it to load the suspension while cornering. Whatever...
I prefer to simply 'double-clutch' when rev-matching, even in corners. I double-clutch/downshift coming into a turn, wait to brake as long as possible, then downshift again [if necessary] and accelerate as soon as possible exiting the turn. This isn't a theory, but a real-world technique. Mind you, I raced cars, motorcycles and ATV's for years. I did a lot of passing in turns, scaring the sh!t out of corner crews and spectators standing by the fences. That was my favorite thing about racing on a track; watching ppl scatter. That's one of the joys that are lost when you desert race...
I use inertia, braking, steering, throttle and suspension loading to get in-'n-out of a corner as quickly as possible, but seldom use the throttle while braking [in a car]. Why? Heel/toeing is V tricky. Your heel is normally 'planted' on the floor and you actually use the ball of your foot on the brake and the side of your foot on the throttle. With some practise you can rev-match while breaking. That is, you can be brake in a turn, blip the throttle and downshift without increasing or decreasing pressure on the brakes. That's the REAL trick.
Personally, I think this is a dangerous game to play on the street. If your foot slips under the brake pedal in a turn on a race track, you'll over-shoot the corner on go into the Armco/hay bails. If you do it on a parkway you're probably going to cause a multi-car pile up.
Anyway, each to his own...
