Just chromatic notes.  He didn't actually subdivide pitch changes,
they were instead transposed, does this make sense?  So if
your original motif was (pitches only) C E, then:

0th iteration:  C                                    E
1st iteration:  C                E                  E                   G#
2nd iteration: C      E       E       G#       E       G#       G#      B#
3rd iteration: C  E  E G# E  G# G# B# E  G# G# B# G# B# B# D##


So, at each iteration, each note in the original motif is replaced with
a copy of the motif at half the duration, transposed to start at the
note we are replacing.  Your suggestion sounds interesting, but that
would make it much harder to hear the self-similarity, I think.

I always wanted to carry this process down to the sample level,
but I never had time to try it.
