You didn't say who the couple was, but Blair and her associates (Golden State Dance Teachers Assoication (GSTDA) went through this proccess. Take a look here. http://www.swingworld.com/wcs.htm I seem to remember she has written at much greater length on this, but can't remember where off the top of my head. Understand that I am merely sharing what I've come across as I research West Coast Swing. While I think there are answers to certain questions, I also think that swing has always been a highly individualistic dance. For me the higher energy level that seems to be accepted in WCS, the lack of the "tanda commitment", and the larger CW community, was what tipped me over from AT, which I concentrated on for 9 1/2 years.
