What else could have happened? Honestly, it's quite obvious that something close to that did occur.
Although, it is debatable that the Arbiter's Grounds is Gerudo's Fortress, but after examining some detail, Thieves' Hideout plus the training ground is big enough to be a dungeon in itself. After all, Arbiter's Grounds is a prison anyway. And with the fortress erected from large blocks of sand, it is highly likely that the fortress faded into ruins within a few hundred years. And with evidence provided that the Gerudo were probably banished to the Twilight Realm (the Gerudo emblem on Zant's cloak for example or that they have mysteriously disappeared, or that they were simply thieves to begin with and their banishment should be anticipated), it seems likely that the Mirror Chamber would have been built in their territory and not off somewhere in the middle of the desert. Also, taking another look at the TP map, Arbiter's Grounds is in about the same place, relative to Hyrule Castle, as Gerudo's Fortress in OoT.
