The excess flow valves in each of the pigtails are designed to allow a small flow of gas so that you can leak check. Another way of stating would be that if you had a leaking line and if the excess flow valve close off completely you would not be able to easily check for leaks, they are designed to pass a small amount of gas which would allow appliances with small consumption to operate but not a gas hog like a furnace.
