It seems like the clutch engages, adding drag between the planetary carrier and the differential's case, thus providing drag torque allowing an opposite force for the front wheel side of the diff to push against in order to raise the torque seen at the front wheels.
I'd kill for a cutaway 3D animation of this beast in action.

So would I. What I am seeing is that the clutch acts in parallel with the planetaries. The clutch effectively provides friction between the same two surfaces the planetaries rotate between. That friction allows the torque split to be varied from 35/65 when the clutch is disengaged to 50/50 when fully engaged/locked.
There is another interesting statements in the last two paragraphs on page "81" that seams to imply the maximum split in auto is 45/55...
