Thinking more about the problem I had to solve, I think it was simply that I wanted to switch at 0V as you said. The switching was unreliable until I raised the other pin a few millivolts above ground.
Probably compensating for input offset voltage error. The input stages were near-miraculous in their day, but not very precise.
