No, he's saying the Troll Archer in Bogus's group is an exception. This may be true, much about Bogus's group is an exception.

But I'm not sure this is an exception. I just ran a quick test with a Lizard Lord, Boots of Quickness & a Bow of War. He definitely fired twice in some rounds. Fired
and moved in others and Fired, moved and fired in one. Similarly with Boots & a Banefire Crossbow, he fired most but not all rounds. And made a partial moves forward.

This matches what I've seen before, particularly with W9 Ancestral Vessels. They would Fire, some of them would advance and some would fire again.

So, I'd say quickness & bows works but not quite as well as you'd expect. This may qualify as a bug. Either firing twice as often or no effect would be understandable, but I can't justify this weirdness.
