The later cars transfer allows this.
Also, I am reading I had the earlier ratio incorrect. Still fixed, but fixed at 38/62.
The video shows an X5 with ZERO grip on all wheels. The later portion of the video shows that the other wheels are spinning at the same rate or close to it until the braking kicks in. This happened quite a bit on my '04 3.0 in the snow and would be expected in that case.

The TC torque split on pre-facelift was 38%f/62%r while driving without tire slippage. When slippage was detected the brakes on the slipping wheels were activated automatically which transferred torque to the wheels with grip. Not sure of the absolute limit BMW programmed into the system.
