Good to know it's better, but it can't be doing the full incremental
version:

  Beginning  with  rsync  3.0.0,  the recursive algorithm used is
  now an incremental scan that uses much less memory than before and
  begins the transfer after the scanning of the first few
  directories  have  been  completed.   This incremental  scan  only
  affects our recursion algorithm, and does not change a
  non-recursive transfer.  It is also only possible when both ends
  of the transfer are at least version 3.0.0.

(says man rsync)
