Maybe they had to reduce the size of the square as they added other sets. Heck, I remember the white sofa, which seemed sooo out of place, and the fires burning atop the ledges. The thing was, that set was supposed to be used "in and out" with the shops being part of set, but instead everyone was outside, it obviously never opened the dome, people even ate out in the square. It just wasn't utilized the way it was originally envisioned, so it does seem that now, it is about the size of Salem Place (which no longer exists - and I have seen that area in person)
