That story might be true, but it isn’t honest to claim there’s no way that Rabbi Schneerson ever at least entertained the possibility that he would be Mashiach.
Rav Shach, in his efforts to prevent Klal Yisrael from falling for the fallacy of Chabad Messianism, stated that Rabbi Scheerson was trying to convince himself that he is Mashiach.
There’s much out there about this topic of Rabbi Schneerson indicating that he is/will be/could be Mashiach. Tablet magazine has a long article by R’ David Berger from secular year ’14, which has many references to Chabad and other publications, at least some of which (the links) are still active, about this.
