I watched the first 10 minutes, until they showed that was an airbus-type flight simulator, then I switched off...that's not an aeroplane, that's a flying computer, designed to flown on auto.
They didn't have any chance to control it, there's no feedback other than visual reference, remembering they didn't know what the PFD was for!
If they had used a B737 for that experiment, I suggest both that I would have watched it, and they would have done much better in the initial test!
But that's me!
Cheers...FD...
