I think that all the Nikon ones behave the same and apparently the 300mm AFS and 200-400 AFS are meant to have similar behaviours.
My 300mm f2.8 AFS the tripod collar will rotate when fully unscrewed it acts more like a clutch or friction control as depending on how tightly you screw it up you can have the ring completely locked or turning under some or no friction.
