Nektarios,
I believe the article in question was from the 1960's.
To answer your question, since we were in communion with the ROCOR, and we don't nessesarily believe that those who you might consider the "ROCOR" have really hung on to Orthodox Tradition, it may be that one day we come to recognize the ROAC or the ROCiE as the grand historic stem of the ROCOR - that is, the real ROCOR.
In other words, just because the pope claims he is of the same lineage as the original Orthodox Bishops (popes) of Rome, does not make it so. In fact, that could not be further from the truth. Without the faith, that is, the Orthodox faith, in Rome, we cannot speak of the Church or a bishop there.
The same is true for the ROCOR, the MP, or anyone else. If the faith is lost or there is communion with heresy, then how can one say they are the ROCOR or even Orthodox??
