On the multi-tasking versions of iOS, double tapping the home button brings up a strip down the bottom of the screen. You can scroll left and right, and it will show you apps that you have recently run and/or that are still running. There's no real indicator to show the difference.
If you scroll all the way to the left, you get a bunch of music options, and the screen orientation lock, which is quite useful since they decided to remove that function from the hardware switch.
Now, while that bar is showing, you can press and hold one of those recently run apps, and it will jiggle and you can force quit it by pressing the x in the corner, very much like removing the app. As far as I know the force quit through this method is the same as the one with the power button and home key thing (maybe a bit faster).
Where your technique comes in handy is that the list of recently run apps does not include the currently frontmost or 'runningest' app or whatever it is. So you can't quit an app while you're in that app using the ribbon technique.
