It's part of the reason why scalar negation was invented in the first place, so you wouldn't be able to say "That's not a brown chair" while allowing the possibility of someone else's saying, "No, it's a Shetland pony". That kind of broadly scoped negation is left up to "na". "Na'e" is much narrower, and implies some sort of commensurability between the concept being negated, and the one being affirmed. Geoff
