This is quoted somewhat out of context, but of course unit demarcation lines exist for some reason, and if upper echelons fail to coordinate and let unit operation zones to overlap, then in the reduced visibility somebody will be where he isn't supposed and/or expected to be, and same somebody will get shot. Now saying this is deliberate does not pass the Occam's Razor test ("all other things being equal, the simplest solution is the best.", sort of)
