The main thing to me is that you have one set of consonants written with a straight stroke, and then a corresponding set of consonants written with a curved stroke.
n b
j d
l y
r s
m g
The column on the left, with the straight stroke, follows a or i but not e. The column on the right, with the curved stroke, follows e but not a or i. o is neutral with respect to this system and may precede letters from either column.
Also, b and j are rare, and it's not clear what to make of these letters. We could remove them and pair d with n, but that would be slightly less symmetrical.
