Taken at face value, yes it's my experience that gunpowder units fire when taking casualties. BUT, the true response to this is it's still broken, my guys still get stuck in the reforming bit and for the most part will not shoot back. They do occasionally shoot, but it's so infrequent and rare compared to how much they should be shooting back is that the real answer in my mind is it's still busted.
