Do you mean "low-energy parts" and "high frequencies", rather than "low-order parts" and "low frequencies" ? Natural images contain most of their energy in low frequencies, so it makes sense to spend less bits on the high frequencies (this is the core idea in JPEG compression).

Anyway, it'd be useful to quantitatively compare the quality of the Daala codec against VP9, which in turn is a competitor to (the probably patent encumbered) HEVC. While it's obviously early days yet for Daala, perhaps the early description of the underlying techniques is a way to mark them as prior art ?
