Can someone explain to me why they don’t recommend putting car jumper cables on the working battery black terminal to the dead battery black terminal but rather to an unpainted metal surface on the donor car?

Question

Also, how does electricity flow from one car to the other if there isn’t a loop?

Umm, where exactly do you get this advise. I have never heard it before, been using jump leads on car battery terminal to terminal since 1994.
