The Greek Orthodox old calendar church being referred to is one that broke from the (New Calendar)Greek Orthodox over the changing of the calendar.
Thank you for the clarification on communion with Rome.
Unfortunately there seems to be alot of misinformation over just who is in communion with Rome. Add to that people not paying close attention to what I'm telling them and it's very frustrating.

The Old Calendarists have actually been re-intergrated into the communion with the See of Constantinople. It is important to note that Old Calendarists as a subgroup of a particuar Patriarchy exist in Bulgaria and Romania in addition to Greek Old Calendarists.

Old Calendar is used by the Church of Russia, Serbia and Jerusalem, because it is the only Calendar by which Pascha is fixed, and all Orthodox Churches celebrate Pascha based on the Old Calendar, even if they use the New Calendar for other fixed observances.

  Some Churches, such a the "Montenegrin," "Macedonian," or "Belorussian" Orthodox churches are not in communion with any other and even do not recognize each other.

  All other Eastern-rite churches (Maronite, Ukrainian Greek-Catholic, Ruthenian, etc.) are Eastern-rite churches (more or less) in communion with the Vatican.
