When talking about distance scales within the universe, you have to be aware of the different ways distances is measured and that when astronomers talk about distance, what you may thin they're talking about and what the are talking about can be two different things. As you can see, there's a big difference between light travel time and actual physical distance. It's something that the public in general aren't aware of, but astronomers just go with the flow as trying to explain it to most people would only confuse them.
