crab,
With no advance angle on either the jacks or the pitch change horn, the swash plate would have to be tilted to the right to enable the disc to tilt forwards (in your example the left cyclic would result in an aft tilt of the disc with the maximum rate of pitch change/AoA/flap down in the 9 o'clock position) On most helicopters the jacks/pitch change rods are organised so that the disc follows the swash plate tilt because the pitch changes are made 90 degrees ahead of the desired disc attitude.
You really believe that that provides a more transparent explanation than imposing a differential lift along a line 90 degrees away from the desired direction into which to reposition the disk?
You can certainly meld together all these changing quantifies to explain what's going on, and need to track the three dimensional paths of the blades, and deal with at least one phase-lag term; but why not just embrace the idea that it's just like any other rotating dynamical system and identify the torques and responses instead?
