It is not as simple as that either. I have seen my horse archers shoot one of their own when chasing off routers. One guy in rear of unit shooting his mate a few yards in front!!!!!!! This has to be mad. Shooting into melee and killing your own will always be a bit iffy and I would expect friendly kills. Whenever possible archers should target approaching units only on FAW, when there is h2h in front of them they should consider dropping back to cover flanks, with FAW off now of course
