The lower part of the bracket (attached to the TV) appears to be double. The two part appear to be pop-riveted together. With this pop-rivet removed, the tv could then be tilted away from the wall part of the mount and lifted off the upper "lip" by which it hangs from the wall bracket. As long as these two "layers" of the lower part of the bracket remain riveted together, the TV will not pull away from the wall part of the mount.
