FYI: I believe if you measure distance at the break the M/R blade cut diagonally through only the upper half of the tailboom structure then the lower structure portion failed downward and tore off. And I think you are correct on the OP video that the aircraft motion is vertical due to the camera angle and optical artifacts. There are other reports that support a vertical decent from a hover after the incident.
