This might have been another reason why she would not have been able to meet her toh in this manner, though Aiel honor being what it is, I would be surprised if this comes into consideration. In LoC & tFoH, Rand is constantly frustrated at how little leeway being Car'a'carn affords him when he runs up against ji'e'toh. For instance, by the same logic, because it was necessry to protect the Car'a'carn, Sulin might have had an excuse to do what she did with the Maidens who were gai'shain, but as that episode makes clear, there are no excuses or mitigating circumstances under ji'e'toh, no doubt because the Three-Fold Land doesn't accept excuses.
