"This will match a query string like tag:nepomuk to a property. It will actually match nao:hasTag which has rdfs:range set to nao:Tag. Thus, the query engine will then look for any nao:Tag instances with a label that matches nepomuk."

Speaking as a beginner reading through these tutorials, I don't understand how rdfs:range is involved in that SPARQL query. Am I mistaken that the query is for properties, specifically properties with a rdfs:label that regex-matches the query string?
