Messian Mode 3

I'm not sure if this answers your question but go to 4:55 for mode 3;

I was taught that scale by a keyboard player/ arr./composer who put out a few albums. I think he called it the major/minor scale. I used it on +11 +5 chords in a horizontal way rather than a linear way.

In the my understanding BH sees Maj7 or Maj9 chords as Maj6 with borrowed diminished notes. B
What do you think?

Why are we borrowing notes from the diminished scale if we already have them?
