This is different data from when xDrive first appeared back in 2005 on the e53 X5…back then it was a 40/60 (front/rear) torque bias.
The info below appears to be inline with the info in the video.

Post a link to this please. Does not look legit to me.
From a more-recent German press release:
"Unter normalen Fahrbedingungen arbeitet es mit einer Grundverteilung der Antriebsmomente von 40 bis 60 Prozent zwischen Vorder- und Hinterachse"
So a base torque split of 40/60 under "normal driving conditions"

Aside from the dynamic 40/60 split BMW has touted for ages, 50/50 would harm fuel efficiency. Much as the Audi front-biased Haldex models operate in FWDish mode most of the time, BMW would operate in RWDish mode, as powering one axle is far more efficient.
