[Erasmus]

[...] the correct term is “antecedent” or “precursor”.

These terms fail to capture the essential meaning element that the work in question was created after the work on which it is based.

For this reason, I also consider the dictionary definition quoted here to be in error, because it also fails to make this distinction; indeed, its wording implies that the "prequel's" production somehow precedes the work on which it is based.

It is the contrast of these concepts--the production of the derivative work following the original, but its narrative preceding that of the original--that is captured uniquely by the neologism. If we need a word for that, and I think we do, that word is "prequel."

Now, as to Godfather II, I am flummoxed.
