I got a two year multitrip visa when I was in the UK. I have had visas before and my wife is from HK and even with an email from the UK (Chinese) consulate stating that it should not be a problem my wife had to argue the point that our HK house stood as a Chinese residence.
It was bloody hard work that involved lots of people staring at us blankly saying I could not get the visa. I think it was only the wife's refusal to budge that worked.
