I think you are reading too much into what is suggested.

The way I would see the "Ambush" arc working is that once tripped by enemy units, the game would ignore/delete the arc and the unit would react as if no arc was in place. The game already has very intelligent programming for reaction of units for assessing threats when no arc is present. By dropping the arc once triggered, and relying on the regular threat determination, enemy outside the originally placed arc would/could/might be fired on. The goal is to have units hold fire until enemy cross a predetermined position and once firing begins to allow targeting to any enemy units within the same turn the arc is triggered. The Cover Arc currently does not provide this flexibility. When using the Cover Arc you have to wait until the following turn to adjust a unit's fire, losing the surprise element and giving time for enemy units outside the original arc to return fire or take cover.
