Not an expert here, but I believe this type of rivet requires the full turn with the end of the rivet material pressed against the backing material. Take a look at a picture of a manufactured brake pad. It achieves it's objective very differently than a solid rivet. It is a lot more like a formed grommet.

I agree

The rivets labeled good, are not good.
Either the tool that is being used, or the technique being used is suspect.

I emailed Matco and showed them pics of my rivets, and like Scott says, none are any good. Turns out the riveting tool I was using is not up to scratch. Matco suggested a screw-type rivet press and so I bought a Rapco Brake Rivet Tool RA825 from Aircraft Spruce and it does a beautiful job. Rivets are now rolled over tight against the backing plates. Easy-peasy like my triplet granddaughters say. Continuous learning process I guess...
