The confusion is in the use of the word churches. In fact, it refers to the jurisdictions of the One Orthodox Church.
The governing body of the Orthodox Church is the Synod, which is the chair of the Apostles and of St. Peter. It is composed of the Patriarchs and heads of the autocephalous jurisdictions/churches and is presided by the first-among-equals Patriarch of Constantinople. His authority as first-among-equals is over the synod, not over any other jurisdiction besides his own or over the church as a whole.
This Synod is most of the time virtual, and the more so in previous centuries. They meet among themselves on occasions and rarely, all of them meet together as happened this year. Not all their meetings are "councils" per se and there are hopes and plans (more hopes than plans) that a council will be possible in 2016.
We also believe this is the Orthodoxy of Catholic governance of the Church, from which Rome deffected in a slow process from about the 9th (Photian Council) to the 14th century (Palamite Councils).
Please, understand that we mean no offense in this, but from our point of view *we* are the Catholic Church, and Rome, once the first patriarchate, left the orthodoxy of catholicism due to its heterodox beliefs about the governance of the church and the filioque. Thus, due to our insistency on the orthodoxy of the catholic faith, we became known in the West as the Orthodox Church, although in Orthodox lands you will hear the terms "Catholic" and even "Roman" being attributed to the church known here in the West as "Orthodox".
The "Roman" being used by us occurs because some theologians and historians understand that the religion that was adopted in the old city of Rome is not the religion of the Christian Roman Empire, whose capital was, after all, Constantinople. These critics believe that a heretic form of Christianity was created by the Franks and eventually by force and cunning, managed to conquer the city and the see of Rome, deposing the religion of the Romans for this new religion of the Franks. In this perspective the Roman church is Roman only in the same sense that the Coliseum is Roman, because it is located in Rome, but not in the ecclesiastical sense of the word "Roman" as meaning that continuation of the Apostolic church, the imperial form of Christianity.
