I don't understand. The captain was in the plane at the time of the
event, so why would "reliving" the event in a simulator help his
understanding? I'm obviously missing/misunderstanding something.

Apparently the snap-roll occured so fast that he didn't realize what
exactly had occured or why. The simulator replay allowed him to see
what led up to the event, and how the event actually transpired.
Remember, he had been engaged in the engine shutdown checklist, and
probably wasn't paying a lot of attention to what was happening until
he realize he was in an upset attitude. At least that was my
interpretation when I heard the story originally...

Here is the NTSB report, but it is very brief and doesn't go into the
detail that I heard from the Boeing chief mechanic:
