its scans to a specific graph. To scan a specific graph, it would have

No... it does not.
We've run into extreme use cases where a graph is created for each
statement (as means of providing properties for a statement). In that
case, Accumulo would not be happy if Rya created a locality group for each
graph.

Does Rya automatically create a locality group for each each graph?
I'm assuming it does, but haven't found any confirmation anywhere and
not got my head around the code yet.
