You know as well as I do that the sidestick takeover buttons are for that very purpose - when you need to either take control momentarily, (to avoid dual sidestick inputs), or stop inputs from the other side due to a more serious problem, (pilot incapacitation, for example).
On Airbus .. you don't check the stick position of the pilot at your right or left .. you check simply the PFD and you know all .. I'm right ?
OK ...
Now Robert ask to descend (as good Airbus pilot he check the PFD) and Bonin answer "OK I descend"
Robert continue "as good Airbus pilot" to check the PFD and see the climb continue ...
Or Bonin just answered "I descend" ..
So now "as good Airbus pilot" Robert can think .. maybe that is something wrong with instrument ... the doubt can take root .. the catasrophe sequence can unfold .....
What if Robert had seen the Bonin stick position ?
This is a infinite debate
