Yes, it usees the full precision. It just "compresses" them into a faster form for the program. The other important part to maximize accuracy is that it uses NOVAS for the Earth frame of reference. Your ephemeris can be excellent, but if you don't correctly a a precise picture of the Earth's frame of reference you will introduce erorr. I believe that NOVAS is the most precise. This is published by the USNO. This is probably like using a sledgehammer to kill a gnat for cel-nav applications.
