I hope that someone here may help me understand the feathering motion of a semi-rigid rotor...

In the 'blown-back' rotor, when a blade moves from A to B, the feathering changes from zero to 'max. down'. In other words, and provided I'm getting this right, the blade 'pitches down' with respect to the tip path plane.
How can this be...? The blade isn't free to rotate around its longitudinal axis...
