Mode confusion is indeed one of the most common problems in human/machine-interaction in modern glass-cockpit airliners, but it is common to all types and manufacturers.
It's not only mode confusion. It's also known or unknown software bugs.
Can you imagine the speed tape (VLS) is going down instead of up if you bank the aircraft (known software-bug on A300) or the FMS guided Autothrust pulls suddenly the speed back in cruise flight to achieve Vapp, but stops at green dot (protection), nobody knows why.....
