LoTR version with new index

I have the 2004 (first) printing of the one-volume deluxe edition of the 50th anniversary edition of The Lord of the Rings. Hammond and Scull state that the second printing (2005) has a revised index and additional corrections. Does this apply to the newer one-volume edition or to the 3-volume version, i.e., if one were to purchase a one-volume leather-bound book off the shelf at, say, Barnes and Noble, would it have the new index and corrections?
