It's either slop or someone without the slightest idea about electricity wanted to make something look complicated without even asking an electrician.

However, the picture looks so stupid that reminds me of those examples gemini was giving about how to wire a switch in which it asked you to connect the phase to the ground or stuff like that so yeah, most probably slop.

Most likely you are correct

I guess paying some electrician a small fee to help them design a realistic wiring instead of that was too much of a hassle for the show. It's so bad that really looks slop.

100% slop.
