He's absolutely right, folks. Check out this aerial image of the POTC buildings and the Indy building. And a minor spoiler that most of you already know:
When you exit the tram and walk towards the esplanade, look for a building behind the monorail tracks, with a faded mural of trees and foliage painted on it. That's the Indiana Jones show building. If you could see through the painted wall, you'd be looking at the dart room, rat cave, and bug room.
The queue is essentially inside a tunnel that wraps around the westernmost shore of the Jungle Cruise river. After you pass through the film room in the queue, you enter the main show building where the ride is located.
Disneyland was shaped a lot like an upside-down trapezoid with rounded corners, back in 1955. By now, the berm has expanded and drastically changed the park's shape; it's more of an oval that gets wider at the top, with Toontown sitting as an awkward rectangle on top.
