The analogy was fine, you're just stretching it too far.

Of course there are times when it's better to leave a "wrong" chord in music, but it's incredibly common for sheet music to have unintentional errors, especially in an ensemble setting. If trumpets are playing a unison part but 1 and 2 have a Bb and trumpet 3 has a B natural nobody thinks twice about fixing the trumpet 3 part. That's the analogy, not jazz and Rachmaninoff
