I'm an idiot and I think I confused the two haha

My thought process based on when I setup my config: "yank copies to my main 'buffer', yank copies to system clipboard through that special 'buffer', and delete deletes without replacing what's in my main 'buffer'. I have multiple clipboards!"

Completely forgot they're called registers and that buffers are just "where text is" (at least as far as I understand it)
