I do agree: The rear disc appears tilted by 15-20° to the right.
Coning is moderate but it's visible. Looks like thrust is still available but massive tilt.
From the front it appears the front Disc ist tilted to the opposite direction:
This might indicate that it was not a swashplate failure, but rather something in the general yaw control assembly.
On the other hand it could potentially also have been an aft swashplate failure countered by the pilots applying opposite cyclic (which then only worked on the front rotor thereby causing yaw).
