I think the author is conflating the document-oriented variant of NoSQL with the whole family of databases. I cannot criticize him for leaving Couch|Mongo if their data is rich in relations, but I would like to read his thoughts on graph databases for instance. Maybe their data is too large for Neo4J, but for querying n:m relationships, this model can offer advantages.
