How someone perceives the same event can vary enormously especially under stressful conditions. Rely on the instrumentation (altimeter and artificial horizon) not on your eyes.
The visual contact with the PF's SS, the seeing of where the SS is at any given point of time, would have given to both PNF and Captain, the immediate, DIRECT, unaltered information of what the PF is doing.

Inferring the positions of the SS from instruments or anything else is INDIRECT information. When the instruments are not reliable it can be lethal.

The yoke would not have made a blind bit of difference in this case.
Of course it would, and not because it's a yoke. Ultimately, it's not about the "yoke" versus "SS", it's about the "SS" problem, which is its positioning in the A330, that can impact an exact, immediate, and precise visual perception of the actions on it.

As I've mentioned it in the past, and will do it again, that using INDIRECT versus DIRECT information, is an elementary system design issue that is known to create problems, where ever is present in any application where immediate and accurate perception of information is critical, one of which happens to be a passenger A/C cockpit.

You're doing very well with your presence on this Forum. Ironically, the quality of the service brought to Airbus does not depend on how blindly one sticks to his mission.
