It does not seem to me that much of anything from the Roman side separates Orthodoxy from Latin Christianity. I think it’s the other way around. The Latin Church recognizes the validity of Orthodox orders and sacraments. That is not reciprocated by Orthodoxy, which maintains that even Latin baptisms and marriages are invalid. Many Orthodox Churches recognize the validity of Roman Catholic Sacraments. I would even say most. The only Orthodox I’ve seen arguing against it were some, not all, Russian Orthodox.
The Latin Church accepts the structures of Orthodoxy. Orthodoxy does not accept those of the Latin Church. I would need you to explain this more clearly before commenting on it.
The Latin Church accepts the “right” of Orthodoxy to be anywhere in the world. Orthodoxy holds that the Latin Church is rightly restricted to the City of Rome and the countryside around it, but has no jurisdiction or right of presence anywhere in Asia, the Americas, or most of Europe. Can you support this with anything authoritative? I’ve never encountered this at all.
The Latin Church does not expect Orthodoxy to depose its bishops and Patriarchs if ever there is reunion. Orthodoxy expects the Pope to resign and be replaced by an Orthodox Patriarch. This is not true. Rome would expect Orthodox Bishops/Patriarchs to resign any post where their diocese would overlap a Catholic counterpart
Now, to my understanding, Eastern Catholicism does not hold any of that, but accepts Latin Christianity as it is. I think it’s a very big mistake to equate Eastern Catholicism with Orthodoxy except in the outward appearance of its liturgies, prayers, architecture, and vestments.
