Eros,
If you look at the local map http://www.eiwpf.org/wp-content/uploads/2015/12/Map.pdfit shows where there are offices within locals. These offices have their own lists. Yes, local 8 covers all of NoCal, but the ranking is most likely only for the San Francisco office.

If the call was a blanket call they would have asked you which office you would like to be listed in whichever one you selected they listed you in.
