There is something wrong with your brake system if it is letting the car back on take off.
We have had 3 of them now in the extended family and not a hint of that. If you have your belt on thereby allowing the auto release, it should not go backwards at all. If fact I read that the system is so intelligent that it senses the cooling of the brake discs and can automatically tighten the brake some more to take up the slack due to the shrinkage of the cooling discs when parked.
The only way it is possible to go backwards (with a properly functioning system) is if you stall or dip the clutch again after it has released and in these cases, you simply do what you would do in any other car... Apply the footbrake and start again.
My car also has an equivalent system (Audi) and if it were to be letting the car roll backwards on hill starts, I would be back to dealer fairly fast.
