H269 Overspeeds

Question for h269c pilots.
The h269c flight manual states that with rotors disengaged maxium engine RPM is 2000rpm above this possible damage to the lower coupling sharft could be caused.
In a practised autorotation if the engine RPM is maintained above 2000 RPM while in the guide is this the same thing as allowing the engine RPM to go above 2000 on start up.In a Autorotation the freewheliing unit disenages the engine from the drive system so to me the engine is under no load and is overspeeding
Anyone who flys the H269C is aware that are all completey different machines, some have good corrrelators some don't.
As an instructor I find especially with new students that if the engine RPM is not above 2000RPM when the collective is raised after skids levels the needles join at very low RRPM especially if the flare rough. And somes students you want the needles nearly joined as the keep you working!
And Help would be much appreciated
