In most cases it doesn't matter, but some appliances like a light dimmer will not work correctly otherwise. If it is a electronic device it will have a capacitor between signal ground and neutral. Faulty wiring will make it possible to get small (non lethal) shocks by touching earth and signal ground or introduce hum in audio devices. So, important no, but wise.
