My own jazzy interpretation of this is that it means something like responsive design by constraint. Think struts and springs and juicy animations sensitive to user-controlled context and the viewport. So an edit button may rarely be in exactly the same place at the same time, given scrolling and device and window size differences, but rather appears, animates, and settles according to a script.

Either meaningless nonsense, or displays a complete ignorance of jazz. You pick.

To be fair, with Android you never controlled every pixel. You just cross your fingers. Also, what a weird image of jazz this man has on his head...
