Maybe he is referring to the loss of tail rotor THRUST as outlined in section 3 (emergency procedure) in the R44 POH. It says "failure is usually indicated by nose right yaw which cannot be corrected with by applying left pedal".
There was an R44 accident in Hong Kong where they spoke a lot about LTE (helo spinning on take off). Was also discussed here if I remember right.
