What are you suggesting? In future suspect that the documentation is always wrong?
No... but definitely suspect that the documentation COULD be wrong... as it was in this case. In 99.9% of cases, it will be fine... but if it just doesn't make sense to you and you aren't sure, dig deeper. That's the difference between a good commander and a competent one.
I'd much rather that than what you are suggesting, which is to always trust the documentation, no matter what.
