Black Hydra can sometimes shoot not where its cannons point

Description

In this clip we see that the Black Hydra ship fires 2 plasma shots one direction follows by 2 in a completely different direction without its cannon turning all the way https://youtu.be/EeFB9Qp3cso?t=24m12s (at 24m 12s)

Expected Behaviour

When retargeted, either it saves those 2 plasma shots until the gun is aligned, or those 2 in the volley are wasted and it must wait for another volley to charge up

Actual Behaviour

It just fires the shots without turning the cannons lol

Reproduction steps

I'm not exactly sure how to reproduced, but I'm guessing that having a Black Hydra shoot a volley at one location and changing its target partway through the volley would initiate this behavior
