If you rearrange what you pasted it makes very clear.
1. "Inadequate pilot training in the application of the unreliable IAS procedure." Read "formality of a demo of UAS procedure was completed during their type rating"
2. "Not understanding the situation" Read " they had no clue as to what had happened"
3. "Lack of structured failure analysis", Read " they failed to plan threat management."
4. "Inappropriate response of the crew" Read " Since they couldn't figure out the situation they decided to do something which turned out to be disastrous.
5. "The division of labor in the cockpit." Read " Since the other pilot was equally in the dark about the situation he could not suggest another course of action and did not take any part in the proceedings."
