It's actually quite common and accepted to fly on one carrier and have miles credited to another carrier's FF program. That's a good part of the reason alliances exist - to allow behavior like that.
It's not a bug - it's a feature.</font>
I think what the original poster meant was that:
Person A flies CX sector, but had Person A's wife's AA number.
Person A's wife got the miles for Person A's flying.
Poster is surprised that CX didn't have some kind of mechanism for checking AA's FF numbers (to make sure passenger name and account name match).
