A few thoughts
You can pin the 2 extras before moving and unpin them after the original arrives.
Or
You can find the the difference of your extra 2 sprites (X,Y) before moving. When you send orig to position you then send copy1 to (X+xDifference,Y+yDifference) and copy 2 to (X+xDifference2,Y+yDifference2).
Or
You need to find the angle and distance you sent your original sprite and then send the other 2 sprites to that angle an distance.
