Fun exercise, but it completely misses the point of modes. This is just a C scale starting on the 1st note , then the 2nd, then the 3rd, etc. It all just sounds like he's playing in C major.
Calling this "modes" is misleading.
If you are jamming in D Dorian - say Dm to G7, it sounds like you're playing in Dm. It never sounds like you're playing in C Major. D Dorian is: D E F G A B C. It HAPPENS to share the same notes as a C Major scale, but it is not a C Major scale. It is a minor scale: 1 2 b3 4 5 6 b7.
It's a bit confusing, but an important distinction.
