How does built in down imaging work on trolling motors if it's turning?

The new Minn Kota trolling motors come with mega down imaging built into the bottom. I bought one and I'm just confused with how exactly the down imaging would work when it's turning in all directions.

From my understanding, down imaging is a thin slice of sonar directly down from your boat, so that targets are clearly separated and detail is increased. If a fish is sitting parallel to your down imaging slice the return will be much less that if it is lengthways like +. If you're moving onto a tree for example, if the motor turned while scanning it, would it completely morph the image and mess it up, or is there real time processing going on to nullify the effect of turning the motor?

Probably a stupid question but.

From what I've studied, there's no intelligent real-time processing like what you have in mind. It will display whatever is underneath regardless of where the tranducer is facing. The object(s) will be drawn on top of each other (don't know which portion is drawn first or last), resulting in not so predictable results. Usually you just get a stretched and distorted image, some identifiable and some not so much.
As a rule, you want to stay in a straight line while passing your target to get the best image. Experience will tell what you're looking at on the screen. GL.
