For great Justice
Looking at the one partially "failed" projectile where most of the petals stayed attatched, that might have been the original design goal. Similar to the HST's mechanism of expanding to points instead of a round "mushroom" to increase diameter and penetration by allowing some material to pass between the expanded petals. Provided it penetrated well, it would have probably given a decent crush/tear cavity, although would have been fragile being the petals are very thin. THey might have had enough money in the design trying to keep it together for a good "traditional" expanding petal mechanism, but failed when the delicate petals kept breaking off, figured they had to much in it to redesign or turn back, and decided to market what they had.
