Left foot braking can be done for very different reasons. First of all, you're probably driving an automatic. It's much trickier to use your left foot to brake when it's also on the clutch. ;) In the context of F1, it allows for less time between being on the gas and getting on the brakes. Not sure if these are used in F1, but I also remember reading about funky techniques where you can use the gas and brakes at the same time to mess with the balance of the car.
