This is for all intents and purposes launch control without having a button for it, I believe 2011 Audi S4s also do just this. No button, you just press the brake in any mode and press the gas.
If you were just pressing brake and gas as you do at a stop, it won't go above 1k. This is the safety cutoff and eventually you'll get brake override.
But if you bury the brake the RPMs will shoot right up and settle, just in the perfect spot for a nice launch.
It certainly pulls better off a start when you do it.
