Adding to the above;
From Airbus A330 Instructors Support Manual -
NOTE:
Depending on the failure type, ALTN is split in 2: ALTN 1 and ALTN 2. In ALTN 2 the roll control is roll direct. In certain failure cases such as loss of VS1g computation or loss of 2ADR, the longitudinal static stability cannot be restored at low speed; in case of loss of 3ADR it cannot be restored at high speed.
The yaw is then also degraded.
It appears the comment on yaw applies to any of those conditions mentioned for ALTN 2.
