Based from what I read of the article, its more about SQL the query language instead of the normal ACID compliant RDBMS over NoSQL databases.
Of course, having a common query language is a big advantage, but NoSQL varies in paradigms and implementation due to the subset of problems they choose to solve, thus having a standard query language does not make sense for NoSQL.
