Exactly! The idea of hidden bonuses is about combinations, not bonuses on individual materia. It would encourage more experimentation with materia combinations, and less of stacking the same materia on the same item. For instance, instead of having dbl meld attack on one piece, and double mld str on another piece, you meld STR+ATT on both pieces to get the bonus (we'll say crit power in this case).
