I have been taught many times that it cannot transfer 100% of the torque to one axle. Wikipedia says the same.

The nature of the Torsen is akin to that of a Limited Slip Differential in that, rather than actively allocating torque (as a computer controlled clutch can do), it supports a torque difference across the differential (the Torque Bias Ratio (TBR)), from the side with the least grip to the side with the most. Hence by nature the Torsen is limited in the amount of torque that can be supplied to the axle with the most grip by the torque available at the axle with the least amount of grip. Therefore if one axle has no grip, regardless of the TBR, the other axle will not be supplied substantial torque. In the extreme, for a centre differential implementation, complete loss of traction on a single wheel will result in very limited torque to the other three wheels.
