Is the Patriarch of Alexandria an Eastern Orthodox or an Oriental Orthodox?

I see Eastern Orthodox keyboard warriors commonly posting memes, bite size apologetics and propaganda against Catholicism which make some variation on the claim "4 out of 5 Patriarchs choose Eastern Orthodoxy. You should too". I was wondering how much veracity is behind this claim. I was under the impression that the Patriarch of Alexandria wasn't even in communion with the Eastern Orthodox church at all. I thought he was a Copt and a member of the Oriental Orthodox communion instead? Likewise for Jerusalem and Antioch. I thought that the only Patriarch of the original Pentarchy that is an actual Eastern Orthodox is the Patriarch of Constantinople? My understanding is that 1 out of 5 Patriarchs chooses Catholicism, 1 out of 5 Patriarchs chooses Eastern Orthodoxy, and 3 out of 5 Patriarchs choose Oriental Orthodoxy. Please help me understand this situation further?
