Answer 1

If you are coming off the brake, then you are not doing heel-toe... the idea with heel-toe is to use both the brake and the throttle with your right foot, while using your left foot on the clutch.  Though, the name itself may be a little misleading as it dates back to a time when there were not standardized controls as we know them, and it refers specifically to early Mercedes racers that had throttle and brake controls vertically alligned, thus heel on one, toe on the other.

In most modern race cars, it's very easy to have half of your foot on the brake and the other half on the throttle.  It can get a little more tricky in a street car where the pedals are generally further apart, though still easy if your feet are large enough - for me, I tend to keep the left half of my foot on the right edge of the brake pedal, angling with my ankle just enough to allow me to blip the throttle with the right side of my foot.

Though this method won't work for everyone... as such the alternate method I've taught when instructing at track events is to apply the brakes mid-foot, more around the arch, or even further back if comfortable, and then using only a slight rotation to use your toes to reach the top of the throttle pedal (I've found this seems to work much better for most than the more acrobatic method usually outlined in books that is more in line with what was used on the original Mercedes, but is now turned sideways for the current control layout).

The full process is to be on the brakes... generally threshold braking if you are slowing down enough that you will need to drop at least one gear... and then clutch in, blip the throttle to rev match, and let out.  If you truelly are braking at the limit of your grip, getting this right is extra important as you will have no margin of error as far as upsetting the car (though typically, you will be doing this at the very end of your braking, and letting up just a fraction will give you a little extra margin of error until you are very comfortable with the technique).

Answer 2

The heel-toe technique is so that you don't have to let the brake up while shifting.  Left foot on the clutch and right foot on the brake.  The right foot leans over and blips the throttle so the revs increase and you shift to a lower gear while letting out the clutch.  This prevents you from disrupting the car under braking and shifting.

wit out ket go of brake.
