It's not that multiple paths to ground are a bad thing, it just can be a bad thing.

The problem arises when one circuit's ground isn't as good a path as going through an interconnect, and then to ground through another component. As long as you have good, clean ground connections on each different circuit they will be preferred over the inter-component path.
