Diamonds concentration in the pastes is 10% to 50%, depending on the brand.
This particular paper wheel has got 3 vials of diamond paste rubbed into it, 20 grams each, since I started using it. There should be some depth of concentrated crystals in the outer paper layer.
As far as my imagination goes, at a higher than the edge angle it impacts the base of the burr next to the apex, breaking it off. Alternating the blade sides, it usually takes 3 passes per side across the wheel, sometimes more. With 0.5 micron diamonds, I cannot see any polish to the apex with the USB microscope after that.
I tend to agree with you that there should be a lesser burr left behind, unless we underestimate deburring effect of a compressible substrate - on a paper wheel it may be closer to stropping than honing.
Its deburring effect may be similar to that of high-angle pasted stropping done by straight razor users.
