Assuming (I know, I know...) that USS Fitzgerald sighted ACX Crystal when she was around point #5 on that chart, wouldn’t normal procedure be to steer a bit starboard and pass the container ship port-to-port, before beginning that eastward turn?
That depends on many factors. What information was passed to the bridge from combat about the contact, did the bridge watch see her. What did the bridge watch determine Crystals track to be based on eyeballs, and the bridge wing compass. The only answers to these questions are found in the deck log and the testimony of the personnel on watch at the time of collision.
