CMIS query returns all versions even though searchAllVersions is set to false

I have uploaded a document with name About Stacks.pdf and edited it few times always incrementing the version number.

When I run following query it will return all versions of the document as result.

ItemIterable<QueryResult> queryResults = session.query("SELECT cmis:objectId FROM cmis:document WHERE ((cmis:name LIKE 'About%') OR (cmis:createdBy LIKE 'About%'))", false);
