The “Yeshiveishe Mesechtas” cycle is essentially a self fulfilling prophecy; meaning, since the Rebbe has mastered the “Yeshivishe Mesechtas”, and not other Mesachtas, he was likely to teach the the ones he had mastered only.
By way of example: I was told, that for years, the standard programming language taught at Brooklyn College was “PL1” rather than “COBOL”. Guess why? Because the professors teaching at Brooklyn College have been educated at Brooklyn College where they were taught “PL1”. As the famous Talmudic dictum goes:
