Because it seems like he's only learning about these rules by reading these threads...
I would add, he seems to be first learning of the existence of these rules in this thread, but somehow is not learning the rules no mater how many times patient posters explain them, still insisting on using Warhammer to resolve everything.
That is why I think he is not a troll. He just seem to have difficulties at reading comprehension (both from game manuals, leading him to totally skipping them, and from the forums themselves).
