I think he means soundtrack is where you write what you imagine the soundtrack of your movie would be like. For example:

1. Main Titles: 3:47

2. Joe: 2:10

3. The End: 8:55

You make up titles for the soundtracks in your movie and assign estimated times. This is actually something I was planning on doing with my movies.
