Ah OK I misunderstood what you were sayingNo, this is a separate thing. You can use launchers like Nova to enable a double tap gesture to hide your status bar up top (pull down) or do other things. I used this extensively before I switched to Action Launcher. Action Launcher has a tap to hide the search bar which I use, however oftentimes I'll accidentally double tap. This would turn off my screen rather than hide an element of the homescreen. It may not be a big deal to you, but it is for a contingent of people which includes myself.
