Your friends in Ops are correct:  We are trained to continue operation
of the engine at idle (or below whatever throttle setting the warning
stopped) if the warning ceases prior to shutdown.  An engine at idle
can still produce enough RPM for a hydraulic pump as well as providing
air for the pressurization system.
