It means more satellites in the constellation(s), and in circumstances where that makes the difference between getting a GPS/GLONASS fix and having to rely on cell tower/WiFi positioning then the difference in accuracy would be very significant.

Isn't that point confirming what I said, albeit confusing redundancy (availability of other systems as backup when GPS fails) with accuracy?
I'm not talking about the entire system failing and falling over to the other, I'm talking about the probability that from any given point you can see enough satellites to get a fix. More satellites is better.
