It isn't quite as simple as you have tried to portray.
Apart from the obvious difference in feel between the levers they are also operated differently.
The flap level needs to be lifted before moving to a different flap position.
The condition levers have associated spring locking levers that need to be pulled up before they will move. That is. you put your hand on top of the levers and and pull the locking levers up with your index and ring fingers to unlock them and then you can move them.
Personally, I can't see how one set of levers can be operated mistakenly. Perhaps there is something a little more sinister being overlooked. However, it's easy for mechanical memory to take over when you are focussed on something else. Also can't understand why PF didn't glance at the levers when she felt a lack of power.
We will have to wait and see...
