This is definitely the most likely answer. I mean, statistically the explanation in the article is almost never going to happen, though I suppose it's possible. But in general the simplest answer is usually the truest and if the guy really believes in his wife he shouldn't have a problem getting genetic testing to confirm it either way.
I mean, if there is ANY question, and in this case it's reasonable to raise the possibility, you should do a genetic test and also an STD test just in case, it's not because you don't trust the other person, it's because you're being sane and cautious.
