ummm, its clear, but is it answering all of the question? I think one of the aspects of the question was around when AF can be revealed. I think Laddin's reply says that:
If the AF effect can be applied any time before the damage or Effect step then you can reveal AF after the dice roll step (before the damage step) and then re-roll the dice.
If I've understood the implications correctly then I guess it is fully answered
The more I re-read the thread the less sure I am - a lot of the question was about whether AF could have an effect on dice already rolled if it was revealed after the roll.... Laddin's answer doesnt explicitly clarify this question.
Quoting an older post:
4th edition, p18: Enchantments cannot affect an event that occured before it was revealed.
and since it can't be revealed during the step...
