I'm guessing that you're referencing the Detroit People Mover family tree here.
What you linked to is the Metrorail, which is an unrelated metro system [[although related in the sense that it feeds into downtown the same way that SEMTA's Woodward light rail was supposed to). Your point still stands though because it's a two way steel wheel/rail system.
The Miami Metromover is what you're thinking of, which was part of the UMTA's [[now the FTA) Downtown People Mover program. While they're both people movers, theirs is a rubber tire system with conventional electric motors.
The Vancouver Skytrain uses the same technology as us [[steel wheels and linear induction motors) and was built around the same time by the same company as us. https://www.youtube.com/watch?v=m9wv6if7fk0
And then since then the same technology as ours has been used to build over a dozen metro systems built by a variety of companies. They can be identified by the metal plates that run down the middle of the tracks.
