Isn’t language a bear! Consider Aristotle and St. Thomas Aquinas.I think this introduced a complication. The Latins distinguished between “Source” and “cause” in the Decree. But the Greeks did not normally do so. I suspect that when the Latin Fathers of Florence wrote “the Son also is the cause according to the Greeks,” they assumed an Aristotelian distinction of Causes, which may not have been evident to some of the Greeks (particularly Mark of Ephesus).

The causes of Aristotle are: material (physical), formal (intention), efficient (agent), and final (purpose). For Aristotle all substance is material (form and matter) but for St. Thomas Aquinas there is a distinction between the essence of a composite substance, which is matter and form, and the essence of a simple substance (finite immaterial substances), which is its form alone.
St. Thomas Aquinas added a fifth exemplar cause to those of Aristotle, and wrote in Summa Theologica, Query 44:
“Reply to Objection 4. Since God is the efficient, the exemplar and the final cause of all things, and since primary matter is from Him, it follows that the first principle of all things is one in reality. But this does not prevent us from mentally considering many things in Him, some of which come into our mind before others.”
At the council of Lyons II, we have: eternally from the Father and the Son, and not as from two principles, but as from one principle, not by two spirations, but by a unique spiration proceeds.
“aeternaliter ex Patre et Filio, non tanquam ex duobus principiis, sed tanquam ex uno principio, non duabus spirationibus, sed unica spiratione procedit”
Denzinger 850: clerus.org/bibliaclerusonline/en/cvq.htm
Note the adverb tanquam “as” which means: as much as, so as, just as, like as, as if, so to speak.
Latin principium means: a beginning, commencement, origin.
Latin procedit (present indicitive active) from procedo: to go before, go forward, advance, proceed, march on, move forward, go forth.
So it is “not as if from two origins, but as if from one origin, not by two spirations but by a unique spiration goes forth”
