The source argument, as you call it, is a searchable XPath expression that
results in a sequence of nodes that limits the scope of the search. It can be a
set of documents, fragment roots, or just paragraph or any other element from
any database document.
The query part acts as a filter, removing nodes from the list of search nodes
that do not satisfy the composed query.
It might be a bit confusing though: searchable XPath expressions can contain
predicates (filters) themselves, and you can translate some of the searchable
XPath patterns into queries as well.
But the big difference is though, that the search always returns a subset of
the source nodes..

I see no reason why cts:highlight would only support cts queries partially.
Haven't you tried yet? ;-)
