Of course, it depends on the features of the store. * Pure RDF stores almost certainly will * Reifying stores might not, because they track each assertion of a statement. This is also a feature that can significantly impact loading speed (imagine checking in a 2B triple store if you've already asserted a statement), so not every system will do this at assertion time.
