Also, the bit about thinking Moghedian was still a prisoner. Nynaeve learned about her escape the same night it happened, so that's a minuscule window for which that datum is relevant.
It seems to me like a whole lot of stuff changed from his mentality when writing the cards to what went into the books.
Sometimes I get the impression, reading these notes, that RJ wrote them half as an attempt to stay organized and half as a way to brainstorm plot points. He wrote them for himself and edited them haphazardly. In this case, he might have been laying out a bunch of things Nynaeve didn't know about in order to come up with something she could discover as a plot point in ACOS, but he did similar lists with a number of characters.
This is part of what makes the notes frustrating. In some ways, they're goldmines of curious nuggets that shed a lot of light on RJ's writing process with bits of plot and worldbuilding that never made it into the books, some of which are clearly post-canon, others of which are not. Alan and Maria apparently had a very difficult time sorting out which were which, and this led to several continuity questions when they had to decide whether or not to include something in the Companion.
But overall, the notes are a jumbled mess of information that, for the most part, has already been revealed in the books. Brandon posted about this a bit on Reddit (see link below).
