The writer is inconsistent with his own storyline. He creates elements that he, later on, forgets or chooses to forget (these elements are pretty big to forget). This has happened many times across all sagas. In Johnathan's saga, Erina Pendleton escapes using the coffin where Dio was held at. But in Jotaro's saga, we can see a coffin retrieved from the bottom of the sea. In Jotaro's saga, we can see polnareff's stand removing armor to attack faster, but he conveniently never uses it again to give the enemy constant advantage. In Giorno's saga, we can see that attacking Giorno's stand would reflect any damage done to the life he created with his golden wind, an eye for an eye, it happened with Act iii freeze and leaky eye. But for enemies' convenience, it never happened again when Ghiaccio froze his wine or Cioccolata turned his branch into the mold, also he had the ability to speed up consciousness and it never happened again after Buccaratti's fight. We can say the writer changed Giorno's stand according to his own convenience in the whole saga.
