You assume that the tip path plane and the control orbit are parallel but the final position of the disc is a combination of the control orbit and the aerodynamic effects.
The blade loses lift on the retreating side and tries to flap down - the cyclic input and therefore the control orbit adds pitch to combat that - the resultant is the high AoA on the retreating side.
Max pitch is at the 9 o'clock as you say but the RBS occurs after that position (hence the pitch up along with the roll) as pitch is starting to decrease so the blade must be flapping down with regard to the relative airflow.
The opposition of the blade trying to flap down and the pitch change arms trying to force it up is why the aerodynamic back load are at the highest just aft of the 9 o'clock (it is why jackstall occurs on gazelle just past the 3 o'clock position - French direction of rotation).
