Double tap the finger print scanner.

Is something supposed to happen when you double tap the fingerprint scanner in iPhone 6?

When I do it the screen moves down half way but nothing seems to be behind it as a function. Any idea what this is about?

Reachability, new with iPhone 6 and 6 Plus. Makes it easier to use the device one handed.
