2003-2005 officials manual had them listed as one signal.

I actually do both differently and if you look at the book, now they are different...over and back starts with your arm extended, similar to how you point to the spot, and then you rotate your lower arm so that your palm goes palm up, palm down...a carry starts with your arm bent and your palm up and you just roll your wrist so that you go palm down.
