From what I understand, you can split apart a hot lead as much as you want, it's when you try to run multiple hots to a single ground you can have issues. If you look at your original schematic, you can see how it has 4 hot leads from a single source, but they all go to various grounds without teeing. It operates fine as a circuit, it just has an unintended effect when the high beam is grounded.
