Why would a rule applied in 40-x.rules be expected to stick when
50-x.rules runs after it and has a conflicting rule?

Change the 40- to 60- and it should work.  Of course, you are already
using another alternative, the last_rule option.

There's a third option that /might/ work, as well, according to the
documentation (which is fresh in my mind due to bug 98175, udev-061's
user/group mixups, today).  You could try replacing the NAME= with NAME:=.
According to the documentation, the := assignment cannot be overwritten,
so that should make your name stick, with newer udevs, anyway.  I think
that functionality is rather new, tho, and may not be in stable versions.
