Devil’s advocate here: if the switches failed electronically (perhaps downstream from the switches themselves) and then the fault rectified itself, the recording on the flight data recorder would be the same. The physical switches may have remained in the RUN position the whole time. The pilot asking “why did you cut off” may have been asking based on engine thrust rolling back, and warnings on cockpit displays showing fuel cutoff active.
Let's analyze your scenario. Both switches happen to fail only electrically but remain in RUN position. The pilot noted that the fuel had been switched off was looking at what? Note the pilot asked about the switched specifically being set to CUTOFF. The pilot did not ask why he lost power or why the engines spun down or at 0% power. He asked why the switches were in CUTOFF. Then in your scenario they started working again.
As far as I know "cutoff" is not lingo for "engine rolling back" The pilot would say "Engine rolling back" Also I am not sure the cockpit would display "Fuel Cutoff Active". I would surmise it would say Fuel SYS Inactive or Fuel SYS Active as Fuel Cutoff Active is a double negative of a condition. Just like the plane would show AUTOPILOT ENGAGED or AUTOPILOT DISABLED. The warning would not be AUTOPILOT NOT ENGAGED or AUTOPILOT NOT DISABLED.
