Comment 2 for bug 348513

As for your second issue about matching the same device, udev(7) currently says:

      "The following key names can be used to match against device properties.
       Some of the keys also match against properties of the parent devices in
       sysfs, not only the device that has generated the event. If multiple
       keys that match a parent device are specified in a single rule, all
       these keys must match at one and the same parent device."

Which is what you described.
