udev rules messed up?

Hey,
I was just testing with all my devices targeting a 1.2 release, when I
found out that the NDISDUP flags for Huawei devices were not being set
properly. The tag setting logic just goes like this:
SUBSYSTEMS=="usb", ATTRS{bInterfaceClass}=="02",
ATTRS{bInterfaceSubClass}=="06",ATTRS{bInterfaceProtocol}=="00",
ENV{ID_MM_HUAWEI_NDISDUP}="1"
After digging a bit in the issue, I found (using ./test/lsudev net) that
upon receiving the udev "add" event it correctly shows the tag we're
looking for in the net device, but just after that we get a "move"
event, where the tag is gone. See both events here, look for "ID_MM".
Any idea anyone? Why is that second 'move' event happening?
