If they have standing orders like “If you’re shot at, shoot back” then there’s still potential for trouble. I think that, in the recent incident, South Korea was holding military exercises in or around places that North Korea claims are part of its territory (claims which the rest of the world doesn’t recognize), and the exercises included things like shooting at targets. So it doesn’t seem that weird for some North Korean guy to go “OMG, they’re shooting at us!” when the South Korea military is nearby and shooting.
