Stranamente definendo il comando e non l’ambiente il maketitle non funziona più. Ho lasciato l’enviroment portando i contatori fuori.
Riporto il codice del maketitle che tra l’altro dà uno strano comportamento con il secondo articolo nel quale l’abstract precede il titolo (mi rendo conto che ciò va oltre le mie capacità)::

Per quanto riguarda la l’elenco autori la definizione degli autori ho effettivamente risolto con
`
\let\authors\@empty
