Note: Even though most of the outside was completed when I went in June, the only time I saw the building was from the Bus parking, I did not go to World Showcase on that visit.
But anyway, from reading John Hench's book, it seems that American Adventure had the exact same problem. The Stage was needed to be built tall due to rising and falling curtains and so a large building was built. I have never noticed it though every time I went to Disney. I will now notice just as I do with forced perspective. Now If I didn't know about the Soarin building, I would be pretty sure I would not notice it at all.
