Wait, so there are two separate cases on the same topic moving through the State SC and the SCOTUS? What happens if we get different decisions, one based on the US Constitution and the other on the VA Constitution?
Either in theory could throw out the districts (as noted, though, the state-level case seems to be over). They can (and often do) have different results under the two constitutions, but that's okay. If the maps are unconstitutional under either constitution, they have to be redrawn, so it's effectively two bites at the apple.
