As for the Re-start in flight
If you've just lost the engine due to lack of fuel and you KNOW the other is about to quit for the SAME reason I suggest attempting re-starting is wasting time, there simply isn't any fuel to re-start with. Time better spent preparing for the inevitable EOL. If in this case Dave DIDN'T know the loss of the engine was due to Fuel and therefore didn't expect the second one to go it might well point to a very confusing and perhaps missing series of displayed warnings.
I know that those that don't do this job find it really hard to understand the modern pilot/TFO relationship and I wont try to convince you how it works in practice. I would just say that if you can't accept what is being said on the subject by those who do it, the same way as some just won't read the report, you are closing off a valuable part of your ability to comprehend why Dave apparently let a fully serviceable aircraft fall from the sky. Or Didn't....
