What they're saying best I can decipher is that seeing that bolt of lightning or that arc from a wire isn't you setting the "electricity" itself. It's you seeing something that it's doing. Like the arc is a shadow puppet and "electricity" as they define it is the hand casting the shadow.

What they essentially want is for you to be able to take a picture of a lightning bolt and zoom in to see the individual electrons moving through the air. Fundamentally entirely misunderstanding how science says electricity works.
