Not OP, but grew up observant. What's meant there is that you choose to not change the state of the electronics. An light that's already on stays on the entire time - you don't turn it off. You end up with an extra set of intentionality - you have to decide during the week if you want lights during the evening in the winter on Friday nights (and if you do, how late should they be on as you're probably setting up a timer on a smart plug).
