He is generally correct about the master but what will probably happen is that the proportioning valve will shut off one end - usually the rears as it senses a failure in the system. That will usually happen if the cylinders and lines are dry. I have used an oil squirt can to fill the lines & cylinders and/or gravity bled the system. Sometimes you get lucky other times they will drive you crazy. It is usually not necessary to run the engine to bleed the brakes.
