Yup...that's what I read, too
Hard to say how this is going to play out. But, one thing I learned real early in my adolescence was if you get in a verbal or even a physical argument with someone, they leave and then come back......shit never ends well. Personally, after the initial argument and they left, I would have high tailed it out of there. If I were still there when they returned, I can fully understand the shooters fear.
