After giving it some thought it would seem that as the blades cone the pitch in the blades is greater than the collective input and the pilot can lift off to a hover with less collective input and if this is the case it is a good thing. However if the helicopter enters a situation where there is excessive flapping on the cone hinges (pitching over, sideslip, excessive cyclic input) when the blade flaps up the pitch will increase exacerbating the situation. The same is true when the blade flaps down pitch is further decreased and this could lead to loss of control.
