The QR is not the only thing that is holding this adjustable stem. Notice that this is a "quill" style stem, so there is a wedge bolt that is used. Check out this picture below which should explain it if you don't know what a wedge bolt is.
Also, I decided not to use this stem, as it's simply too long for me. I need to find something like this, but shorter if I wast to use bullhorn bars. If I use a flat bar, I might go back to this Satori-ST adjustable quill stem.
