Correct, I used to do a bunch of LAS-LAX-SEA flying when AA credited at 100% and the codeshare price on alaskaair.com was often reasonable, AA on the short segment, AS on the long one (often with upgrade). You basically turned a 866 mile flight into a 1454 one with a reasonable connection. This was pmVX so an all-AS trip wasn't an option.
