i am unsure what you intend your formulation to mean.
i do not claim "regardless of the semantics".
i suggest that one can choose a definition - from among 3.1--3.7 or elsewhere, given which an interpretation of a given question is possible in the context of the constructed dataset.
this is more a matter of "dependent on", rather than "regardless" (given its possible connotation of "independent of").

yes, because a combination follows from sparql's conformance requirements.
one could choose some other combination.
one would then have a different query language.
dealer's choice.
