The shape of space

I may not understand an answer here but I need to ask the question.

We have a hugely red shifted proto-galaxy 'A' in one direction, maybe 12+ billion ly distant and in exactly the opposite direction we have another, 'B', exactly the same. It's not possible that A + B are 24 billion ly distant.

I think the problem is an assumption that there is an observer-invariant answer to "how far apart are they?". We would say Yes, they are 24 billion light years apart. They havent seen each other "yet" (again from our persepective).
