Well, Russian bloggie audiences were also wondering re the accepted ? culture, habits and ways, in the Polish crew. Hard to tell, on one side - Warsaw Block heritage, on the other hand - NATO.
One would think it's not for nothing, that even in Civil Aviation in Russia the Captain has been and is called "KVS" - Commander of the Flying Vessel". On the other hand, there were put forward many suggestions by Russian aviators that "in this case the team didn't back up the Commander properly, while operating a TU is a must to be a team work, it is not a small military aircraft, only all together or it's a fail. This looks like a matter of team work failure."
For this matter, one of the most frequent questions asked on the Rus. side - was "how many years they are together?" (the interest was not the separate flying hrs of the crew members) It is strongly suspected (on the Rus. side that "abroad it's another culture, they pride in training crew members separately so well that they can be mixed and shifted in all possible combinations, and they change crew members specially and on purpose." While traditional approach in Rus. has been described as aiming for as little rotation as possible, reaching perfect understanding and how to say, automated all together work, that they rely on each other and understand each other from a glance.
Different cultural approaches may exist indeed.
