The green triangle means only that the torpedo will run a straight line (or close) out of the tube. It doesn't take AOB into account, precisely because you may have good reason to shoot at 30-40 AOB (magnetics, as you note). You can get a green triangle at any AOB.

Yes, I think it represents the chances of the eel making the correct turn to the prescribed gyro angle as it comes out of the tube.
