Whilst entering auto from a VR state may theoretically remove one of the contributing factors, I'd suggest that you consider the design of the particular rotor head. Entering auto from level flight, the rate of descent builds up slowly. Imagine the shock loading on the head if you already have a rate of descent of 2,000 ft per minute and suddenly flatten the blade pitch to present its full surface area to the RoD airflow. It was the great Bill Barrell who advised me (many years ago) that the technique was inappropriate for teetering heads particularly. I think his exact words were "Don't be a f#*king idiot!"
