How does bitUSD work on Peertracks?

-Is it a different bitUSD from bitshares bitUSD?
-Does it have to maintain it's own real USD peg? 
-How will it interact with bitshares bitUSD (fungible, exchangeable)?

I'm worried that Peertracks bitUSD is a separate bitUSD and that it will have to maintain its own peg to the dollar. I feel like bitshares is the exchange and everything would be more efficient, intuitive, and beneficial to the system as a whole if all bitshares toolkit projects, including peertracks worked off the bitUSD established by bitshares. Splitting up bitUSD is splitting up network effect and making each peg weaker.
