Dunno...I went back and reread the
PR, but the only section
I could find that seemed related was this paragraph on Traction
Control which seems to "numb"/delay the onset of the DSC.
Or, it could be a tweaking of the XDrive itself...
Hard to know at this point.

Dynamic Traction Control for greater spin and more dynamic performance.
Reflecting its high standard of driving dynamics, the new BMW X5 also comes with Dynamic Traction Control. All the driver has to do to activate the DTC mode is press a button on the center console. This raises the threshold for intervention of the engine and brakes by DSC, allowing the BMW X5 to set off smoothly on loose snow or sand with the drive wheels intentionally spinning slightly. Last but certainly not least, DTC promotes an even more sporting and active style of driving by allowing more wheel-spin before intervening.
