I don't see why these would not be synonyms (!)."

To make sense of this, you have to keep in mind that these terms are
descriptions of when the leaves appear.

Hysteranthous does describe leaves which seem to appear after the flowers.

Proteranthous however describes leaves which appear BEFORE the flowers.
