Yea, you are logically right, I guess what I was thinking is destiny's story explains that there are other guardians in the universe that are fighting against the darkness and how you should join the battle, where in borderlands, it doesn't matter how many people your playing co-op with it still refers to you as one person. So if we're talking about the universe the developers wanted to create, there can be infinite players in the destiny universe were there is really only suppose to be a couple vault hunters...
