It doesn't matter at all, as the braided wires (from the pickup and
from the switch) are still being grounded. It would only pose a problem if there was a live wire touching the braided grounds - which could cause a short, or cause the guitar to work intermittently.
Basically, if a ground touches a ground anywhere in the circuit it won't matter, since they'll just be grounding to each other.
