I would've expected him/her to complete an autorotative landing per the RFM procedure for a complete loss of TR (twist grip to IDLE) to avoid the uncontrolled yawing we see near the end of the video... The other helicopter surely would have been able to radio to him/her that his TR was ******, so that would confirm to him/her that a power-off landing is the correct procedure. Regardless, job well done getting it on the ground with all the meaty stuff inside still breathing and hats off to the pilot.
