You may notice that I was referring to "the cylinder", as in singular.

Even if you control the cylinder at the hips, it may not roll about the access of the cylinder, but the top can still move side to side, and that is what I have witnessed the most. This is specially true when the shoulder harness is adjusted to allow the cylinder to ride low, for the regulator to be between the shoulder blades.

Out of the water with gravity holding the cylinder down, it looks like it is going to work, but it doesn't look as good in the water.

Actually, that statement is not quite right. If the harness is adjusted correctly, the hip connectors work well to stabilize the cylinder. This comes from four decades of diving that setup.
