Friend Hit (dialogue) behaves differently than original engine

Is Friend Hit working properly in OpenMW? The moment you kill the follower NPC it will return 0. so it doesn't register friend hits if you outright kill npc unlike the original engine so you can't use Friend Hit dialogue filter from Construction Set for mods. The spoken part of friend hit works correctly.

Friend Hit (dialogue) Used in dialogue for when you attack a member of your group (like a follower) The return values are:

0 = never been hit

1 = hit by pc 1st time

2 = hit by pc 2nd time

3 = hit by pc 3rd time

4 = hit by pc 4th time and the npc/creature is not in combat with the PC

Friend hit will reset if the player hits a different actor. It also appears to reset if the actor starts combat, even if there are no hits (I tried "ActorID->StartCombat ActorID" - i.e. "start combat with yourself" - in dialogue results, and this seemed to reset friend hit).
