That's exactly how it worked! The "clip" is the BMW version of one of those white plastic acorn or bayonet trim fasteners that are used on most all cars. If it stays behind, it would probably simplify replacement to remove it from the A pillar and replace it on the trim. It came out with the trim on mine. Getting the trim piece back in was a little more of a challenge, but eventually it popped back in place.
