Is the fitness test the biggest problem with mixed groups?

I read on Quora, that the real problem with men and women fighting together, that if both a man and the woman is caught as hostage, a man can't see a woman from his team suffering, and gives up the secrets much easier.

There's plenty of potential problems with mixed groups but I don't really see that hypothetical situation being a major issue.
