Not necessarily.
In previous Low RRPM Rotor Stall Mast Bumping accidents the Rotor stayed on longer than the tail boom in most instances, sometimes it stayed on until the ground.
However if it was a straghtforward (Pushover type) Low G Mast Bumping w/o low RRPM it could lead and has done so in the past to a loss of the complete Rotor assy.
The only other 'typical' reason for losing the entire head is M/R blade fracture. But in this case you would expect one blade separated (at least partly) from the hub.
So far this case does not seem to show completely untypical signs for a Robbie accident.
