[master] Npc double emotes/animation.

I found some NPCs that have double emote animations, for example

Does anyone have an idea of how to implement this? That screenshot was taken during MoP, but still actual for Legion. It looks like this NPC use strangulate emote on his lower body, but something else on upper. I can’t find anything related in sniffs, maybe it’s anim kit or whatever, but there are only zero values.

This screenshot is showing korkron scout from Ragefire Chasm. There are two of them using this animations and one under the dog in the beginning using “sleep” animation for lower body and “punch” for upper. Any help would be great since I’m working on Ragefire Chasm rewrite and going to release it when it will be done completly. Only minor graphic fixes like this and few quest related issues left.
