This is what the November 2017 Watchtower states
Beginning in the late 19th century,The WatchTower drew attention to the prophetic significance of the cities of refuge. “This feature of the typical Mosaic law strongly foreshadowed the refuge which the sinner may ﬁnd in Christ,” stated the September1,1895, issue.“Seeking refuge in him by faith, there is protection.”
A century later,The Watchtower identiﬁed the antitypical city of refuge as “God’s provision for protecting us from death for violating his commandment about the sanctity of blood.” However,the March15 ,2015, issue of The Watchtower explained why our recent publications seldom mention prophetic types and antitypes: “Where the Scriptures teach that an individual, an event, or an object is typical of something else, we accept it as such. Otherwise, we ought to be reluctant to assign an antitypical application to a certain person or account if there is no speciﬁc Scriptural basis for doing so.” Because the Scriptures are silent regarding any antitypical signiﬁcance of the cities of refuge, this article and the next one emphasize instead the lessons Christians can learn from this arrangement.
It is highly unlikely that any JW would get the significance of this 'new light'. Very few JWs would know that Rutherford used the Old Testament "Cities of Refuge" arrangement to support his Other Sheep theory in 1934 and 1935. However, it is highly likely that the writers of this statement knew exactly the significance of what they were saying. After all, they researched to as far back as 1895.
It took Meleti, a very talented writer and researcher of Beroean Pickets, a great deal of effort to work out what scriptures, if any, the organization used to base it's 'other sheep' teaching on. He searched 2,233 occurrences of the 'other sheep' within the Watchtower library dating back to 1950 and the search didn't stop there. The only basis for the claim that Meleti could find was this silly interpretation by Rutherford.
