That's very awkward. Different rules in different states I guess. I never was asked to show mine (as of yet).
Shep, first of all I don't think the -copy- of the BC will do any good because you usually have to show the original anyway.
But to show real BC I can think of couple reasons. First, if his UK passport expired they may ask for BC to start issuing a new one. Second, if he decided to drop his UK citizenship (and it's one of the requirements to work in certain places or (I believe, but not positive) to do the clearance of certain level). I'm sure there are other reasons too.
Why not to ask his wife directly if you are concerned?
P.S. And I'm sorry about your mom! :(
