This would explain the pilots' statements as transcribed in the report.
Why did it take 10 seconds to switch back to run? Speculation: Perhaps noting that fuel supply was in a cutoff state even though the switches were in the run state, one of the pilots toggled the physical switches to cutoff, waited 10 seconds, then toggled them back to run.
More analysis of the recorders is needed to determine exactly what happened.
