Very well explained.
To illustrate this point, the schematic of the control system, (note that AP box channel is treated like a Pilot imput channel):
And the AIB annexe to the report quoted above on A330 behavior in full auto flight facing turbulences. (There is no THS track, but the FCPC would not have time to adjust it anyway, as such pitch corrections are mostly left to elevators and autothrust).
