To be fair they do point out that ATC will be frantically trying to find someone groundside who knows what the 737 controls look like so they can specifically talk you through actual control operations.
This is the worst-worst-case scenario if they somehow can't find someone within comms distance who knows what the inside of a plane is like for some reason so... uh... best not to fly redeye. On New Year's day. On a Sunday. Or something.
