THEN, your final challenge in the second half of the game makes you go through the same room, but east to west. It's a cool parallel that nobody really talks about.
Honestly, I think that's one of my favorite parts about the Johto games. You just go all over the place. It feels a lot more winded of a journey than the other games.
