From what we've seen in the previews, it seems that ships can move multiple 'segments' worth of distance in a turn - how many depending on their stats and action choices. And then can - from one segment to another - 'pivot' each element a certain number of ticks based on their stats.
Assuming I have that right - let's take the example of a ship doing a right-turn at 3-segments-forward. You'd have to adjust the first segment one click to the right...next segment to whatever the first was and one more click to the right...third segment at the second value and one more click to the right...and done!
Next turn, the ship wants to swing the other way, same deal. Now you've got to pivot the first segment to the left...next segment swinging over 4 positions from where it was so it becomes 'first left segment +1 more to the left', and even more adjustment needed for the third position...
I guess the question is...why?
Why not just use two segments with one pivot? Put it at the starting point on the ship, move the ship to the end point...then pick it up, click it one to the right, move it to the front, again, and move the ship down it...then pick it up, click it one to the right, move it to the front, again, and move the ship down it one last time.
Seems a lot less fiddly, and takes up a lot less table space...
