It was more about seeing a piece of good architecture from any angle. The designers of the original park were proud the pavilions looked good from any angle. Even the back. Such was the scale and depth of EPCOT Center.It's more about when you're walking through from the plaza. Like Horizons, and The Land sight lines were mainly from the center..
Horizons and Energy BTW were designed to look great from the back and the sides. They would have been clearly visible from these angles from the LBV monorail.
