Apparently Cardinal Mahony and the Episcopal bishop were golfing buddies, so can't have any "sheep stealing"...which nobody ever complains about when it's Catholics going over to another religion. If the parishioners of St. Mary of the Angels wanted to be Catholic, the golfing relationship between the Cardinal and Episcopal bishop shouldn't have been an obstacle. 

Thankfully Archbishop Gomez is more tradition friendly but after all the legal battles and all that has changed over the years who knows if St. Mary's will still join the Ordinariate?
