In this launch scenario, the forward speed of the car never fully matches the wheel rotational speed (there's still some spin occurring even when you grab 2nd). The idea is that by dumping at a low RPM, you'll rely on lower power to moderate wheel spin, rather than the throttle.

This may not be the most optimal technique, but it's often more consistent. In a car like the M5, moderating the throttle on launch can take a *lot* of practice. There's so much power on tap, and you're dealing with a turbocharged engine, so the torque curve shoots up at low RPM as the turbo spools. While in motion, the turbo lag is managed well, but from a full stop, there's no avoiding it. These types of launches will yield more consistent results.
