You keep stepping on every plate you see on the way south, however you jump the one that leads to the southwest path, so you have a way to go back. It looks like there's a button at the end of the new revealed corridor, but it's also under a pressure plate. You could easily jump there, but you could also just ignore the button entirely, maybe it's just here to trick you.
