Thompsonbry.systap added a comment. This depends on how you model the reified RDF data. However, the inlined statements about statements are not in the same part of the statement indices as the ground statements. This is because the IVs all have a prefix byte that includes whether the IV is a Literal, URI, Blank Node or Statement (inlined statements about statements support). So the statement indices are partitioned on each component of the key in terms of whether that key component is a Literal, URI, Statement, etc.
The way this works normally, you have a ground statement like: <:a :knows :b> You then have statements about that statement: <<<:a :knows :b>> :source :facebook> <<<:a :knows :b>> :date "1/12/2015"^^xsd:dateTime> Those statements about statements have the inlined statement as the first component of the key for the SPO(C) index. Thus they are clustered together, but not cluster with the original ground statement.
