They disguised it as narrow pathways that blocked the line of sight of the old and new area and while you ran there the game was loading in the new zone while phasing out of the old one outside of the players field of vision.
This reminds me of somethign WoW did in a lot of its city entrances. You walk in the gate, and there's a wall you have to run around before you get into the actual city to buy time for things to load.

In Metroid Prime new rooms would load when you shot a door to open it, and you could tell sometimes it was struggling when it'd take several seconds for one to open.

Little disguises like that for load times aren't all that uncommon.
