Do you have a reference that explains why this is the case? Should 
we only act on "change"?

The comments in the rules file explain this:
 http://git.debian.org/?p=pkg-lvm/multipath-tools.git;a=blob;f=kpartx/kpartx.rules;h=f32c7186acec86096bd5930a27d5430cb21ae60a;hb=HEAD

The first part is for creating persistent device names. The second
(kpartx) is for creating linear mappings for the partitions on the
device.
