You're spot-on. At night, the luminous part of a high-vis is useless, they're designed for day use. The 3M reflective strip reflects light back only at the light source. The effect is one of those modern miracles of material technology. "LOL where are the batteries!!?"
But while it's impressive, it's borderline useless for rear-view mirrors, which do not shine a light back at the cyclist.

Retroreflective strips reflect light back from the source to the viewer. In the case of a rear-view mirror, the light source is the tail light of the vehicle, which will hit the retroreflective material, reflect that back towards the vehicle where it will be seen by the driver in their rear-view mirror.
