Jack, you are right...what Sink Rate alluded to was " blindly " following the checklist and thereafter " blindly " ( highly unlikely, but does happen ) crossfeeding in " normal fuel management ". It is certainly hoped that this will not happen but in a stressful situation coupled with rapid loss rate and unreliable totaliser/fqi one cannot discount such possibility.
Mind you, I have seen 3000+ flight hours F/Os with ATP who are made cruise captains fouled up fuel management in this fashion in the simulator LOFT with fuel leak/engine leak problems!
