Sadly it's not the case! You can encouter this model in game in a lot of places, and very often it's being used as a path/bridge, on normal, playable maps. The top view is its "main" view. That's this model's purpose, to walk on it. But in the normal game, it has a much better quality, just like the layer underneath the pixelated texture, visible on my screenshots. The HD texture is still present, just covered with low-res mess :( Strange indeed. The only reason I could think of would be to limit the textures that would need to load since a lot can be crammed in to a small space inside guild halls.
