How does SLComposeViewController display the displaying viewController in background?

How does SLComposeViewController display the displaying viewController in
background?

I thought if we display something modally, the viewController in
background will be completely filled.
Yet SLComposeViewController did it differently. We can still see the
viewController in background partially.
How did they do so?
Is this new in iOS 6?
