I was curious about this myself from this post and dug this up from the 2018 .PDF Manual:

Natural Arrangements (re-interpret complex chords)
If you give a pro musician a complicated chord progression with fancy extensions like C7b9b13 or Gm11, the musician may reinterpret these rather than playing them exactly as written. This can achieve a much better sounding arrangement because the musician has freedom to choose from similar chord extensions. You can get Band-in-a-Box to do the same thing with this option for all tracks in all songs. (Note: To set this feature for all tracks in the current song, use the option in the Song Settings dialog. To set this feature for all tracks in all songs, use the option in the Arrangement Options dialog. To set this for specific track(s) in the current song, right-click on the track radio button, go to Track Settings | Set Natural Arrangement, and select an option.).
