I don't think this is a nod to Horus. Horus was the good guy. Set is Satan/Saturn who murdered Osiris, Horus' father. Set gouged out Horus' eye in the battle, but Horus still defeated him. If anything, I think the cabal use Horus' symbol (the eye of Horus is a protective symbol of good) like they do the swastika- they take symbolism that initially meant good things, and pervert it. I think their use of Horus' eye symbol is an eff you to Horus.
