Definitely not power settling. He brings the cab into a downwind hover (watch the fireman hosing it down after, fire crews always aim the foam downwind(given the choice) which is the same direction the helo is lying, so assuming he didnt yaw prior to landing he's downwind. The cab initiates a "fast" stop, then descends because he doesn't pull enough power and you have the classic symtoms of incipient vortex ring. Not enough height for fully developed VR, hence only a reasonable but unacceptable rate of descent on landing.
