Query Folding and Query References

Hey folks, I can't find the answer to this in the docs, so maybe someone here can clarify.  I have a Power Query script that pulls data from a SQL Server table.  Call this query A.  This query folds just fine as indicated by the fact that I can view the native query in PQ.  If I create a new query that references the query A (call this one query B), I can't view the native query.  Am I correct in assuming that the reference to query A breaks folding for query B?

We use a stage/load pattern for all of our PQ development where we stage untransformed tables but don't load them to PBI.  We then do any transformations against a reference to the staged table and then load the transformed table to PBI.  If this breaks folding then we'll need to rethink our approach.

Thanks!
