This method is commonly used nowadays as it is efficient than the two wire control system. Black wire power or hot wire.

Two Way Switched Lighting Circuits 1
Two way switch connection. A 2 way switching connection means you can control an electrical equipment like bulb by two switches placed at different places generally used in the staircase. At the light it connects to the neutral terminal. Two way switch can be operated from any of the switch independently means whatever be the position of other switch onoff you can control the light with other switch. We look at the eu colour coding wires. It is also a new method to make a 2 way switching connection as it is a little different from the two wire control method. When wiring a 2 way switch circuit all youre really doing is controlling the power flow switching offon to the load a light lamp outlet ceiling fan etc now a typical circuit will contain a 3 wire cable known as romex.
To construct this setup we need 2 two way switches here common terminal on one switch is connected with phase line and another switch common terminal connected to the lamp load always prefer switch connection in the phase line.
