Its a foolproof way for a proper How to determine the correct wires to attach to a 3-way switch when the wire and screw terminal color code is not certain.
A4-way switch is an extension of the 3-way switch system and is used in combination with multiple 3-way switches to control a light from three or more locations. It is commonly used in larger rooms, such as conference halls, where several entrances require control over a single light fixture.
Thekey to understanding 3-way switch wiring is realizing that the electricity flows from the light fixture to one switch, then to the second switch, and back around to the light. The switches simply 'disconnect' to turn the light off. One of the switches will have an additional traveler wire that allows the switches to communicate. 3Way Switch Wiring Methods.

Ifit was wired with knob and tube originally, it's possible that the 3 way switch was old enough to be wired as "Carter 3-way": Image from Popular Mechanics, October, 1971. In this setup, the load is switched between H-N (on), H-H (off), N-H (on), and N-N (off). Since the 3 ways have the load on the common terminal, the "travelers" can
