From the photos, it looks like the Turbo S understeer around the curve, caught a lot of air (see the freshly exposed wood fibers high up on the tree trunk). Might of impacted right behind the B pillar at the roof line which would then cause the Taycan to pivot around the roof right down into the doors and then rotate around the trunk into its final position.
That is a frightening hit and I don't think there are any tests for that kind of impact. Trees don't move so if you hit a tree it's going to hurt BAD. Even worse when your vehicle weighs 5,000+ lbs. The heavier the car, the more force there is and when what you hit doesn't move, all that force (F=MA) is going right back at you thanks to Newton's 3rd law of motion.
