No, heel-toe is used to match engine RPMs to drivetrain speed when downshifting enetering a corner. At the limit of a car's braking capabilities, and most prominent in RWD cars, but still true to a degree in FWD and AWD cars, not properly rev matching can upset the balance of the car by slightly locking up the drive wheels. This can cause the drive wheels to have a left lateral force (long physics discussion as to why it's left, way beyond the scope of this post), and can cause serious problems. Done correctly, you are using 2 feet on all 3 pedals simultaneously.
If you're looking to shave time from the brake to gas pedal transition, learn how brake with your left foot. I brake with my left foot everywhere on track where I'm not downshifting. This is a highly advanced technique, takes a lot of getting used to, and is not reccommended in a manual car for street driving.
