No - the yellow pump is a PM task and independent from the engine shut down which is the important bit. Set the parking brake, confirm it's on, and shut down ENG 1. There's no requirement to wait for the pump to go off, although I delay it a second or two to ensure the accumulator is topped off when the park brake is set.
