The official answer is that the nuevo-anointed are "replacements"

w99 2/1 p. 19 Our Treasure in Earthen Vessels ***At a Gilead graduation in 1970, Frederick Franz, then vice-president of the Watch Tower Society, told the students of the possibility that they, who were all of the other sheep with earthly hopes, might baptize someone who might claim to be of the anointed remnant. Could this happen? Well, he explained that John the Baptist was of the other sheep, and he baptized Jesus and some of the apostles. Then he went on to ask whether there still was a call for gathering in more of the remnant. "No, no more additions!" he said. "That call ended way back there in 1931-35! There are no more additions. Who, then, are the few newly associated ones who are partaking of the Memorial emblems? If they are of the remnant, they are replacements! They are, not additions to the ranks of the anointed, but replacements for those who may have fallen away."
There were 5 more partakers in 2004 than 2003.
