NEC Art. 225.30 makes this rule. The reason is for safety. Lets say you have two circuits feeding a building and you turn one off. But do not realize there is another power source that is still on. You still have power in the building. You want to kill all power with one breaker. So a feeder or multiwire branch circuit would be the choice.
