Looks like a good design actually.
HF forms directional beams and bounce off stuff this is what we already know (or you can know it after seeing speaker measurements on this site). The graduated holes help to form a narrower beam while also steering the beam direction. Side-bouncing / ceiling-bouncing tweeters are not new but this implementation is unique.
