To me, the use of the word "taken" is the tricky point.Well, doesn't the same current that the switch supplies also come through the breaker or fuse? Isn't that same current being 'taken' to supply utilization equipment traveling along the entire length of the branch circuit conductors? Does it not flow through the meter socket? The service conductors? Aren't they all 'a point in the wiring system'?
An outlet occurs in a switch that is used as a controller.
Take a look at the Article 100 definition of Premises Wiring (System) and you will see that wiring internal to a controller is not part of the Premises wiring system.
404.14(A) tells us that a common snap switch is used for "controlling" the loads specified is 404.14(A)(1) through (3).
For the current, being taken by the utilization equipment, to pass through the switch, used as the controller of that same utilization equipment, the current must "leave and re-enter" the Premises Wiring (System).
At least, that's the way I read the definitions of Outlet, Controller, Premises Wiring (System) and 404.14(A).
