Yes, I'm guessing.  ;-)

The cutouts are supposed to promote even wear over the full face by 
preventing the uneven wear that happens normally when you press a pad 
against a surface that is moving "sideways" with respect to the pad. If there 
is something wrong with the cutouts or the hardware, it could cause a 
problem.

I suspect that typical Brazilian calipers wear the lower edges MORE, rather 
than less, but that the difference was small enough that the makers decided 
no one would notice enough to complain.

Whatever the cutouts do, or don't do, they do it for both inside and outside 
pads. So I am left with bad machining or alignment hardware out of place.
