As you turn the steering wheel, the coil of wires within the clock spring winds and unwinds, maintaining an electrical connection for the airbag and steering wheel controls.
Regardless of how much you turn the steering wheel and in what direction, you always keep a connection between the airbag control module and steering wheel airbag, the radio and its steering wheel controls, the horn button and the car horn, and any other buttons or controls on the steering wheel to what they operate.
You may be thinking that the clock spring plays a role in returning the steering wheel to a neutral position, but this is not the case. The reason a steering wheel returns to its centered position when you let go of the wheel is because of the vehicle's caster angle, not the clock spring.
Most vehicles have a positive caster angle. When the front wheels are turned, a positive caster angle puts force on the front tires that makes them want to return to their neutral position, pointed straight ahead.
Since the steering wheel is directly connected to the tires, the steering wheel is affected by this centering force. Besides, a real spring this small would likely not be able to overcome the inertia of most vehicles' steering assemblies.
