Question: If I follow his advice, how would I get the new synthetic brake fluid into the system? Would I simply add the new brake fluid to the master brake cylinder reservoirs?

Use the air pressure to move most but not all fluid out of the reservoir, then remove the pressure bleeder, refill the reservoirs with your new fluid, apply the air pressure again and again use that to move most but not all fluid out of the reservoirs, repeat until the flush is completed.
There is little advantage and some disadvantage is doing it the way the other poster does when in your situation you are aiming to do a complete flush rather than a simple bleed.
