ELI5: Passive sonar gives you the opponent's bearing only; Active sonar gives you the opponent's bearing and range; active sonar gives your bearing to your opponent(s); firing a torpedo gives away your bearing to your opponent(s). Why wouldn't you confirm a solution with active sonar before firing?

Maybe you don't want to give yourself away!

Sonar ignoramus here.
Can't you get the bearing and range with passive listening from two points, and/or single point but measuring over time?
As for why not to confirm a solution with active sonar before firing; if what you described are rules of the game, then IDK because it doesn't seem to load anymore. In real life, I imagine an active sonar ping being much clearer and more informative to the enemy than the noise generated by launching a torpedo.
