This is a phrase that some of my friends and I used to say to each other, just as a term of endearment or agreement or support. I suppose it's a silly phrase, as sameness doesn't necessarily mean that you're going to be good friends with someone...but the thing is, we weren't the same. We were a rag-tag-motley-crew bunch of random college students working on staff together at summer camp. We came from different backgrounds and cities and upbringings and we had varying strong opinions about everything, and yet...we were such a little family. I liked when we would say this to each other because of how different we really were - it was like saying that none of that mattered. We were friends. We still are. So that's the same, too.
