It's not called randomly. It's called every time the name/skin packet is sent to a player, which is done by the server every few seconds. The event doesn't notify plugins about players using the commands, but about outgoing update packets.
That's why the example code sets the nick/skin every time the event is called:

@EventHandler
public void on(NickDisguiseEvent event) {
    event.setNick("inventivetalent");
}
