Well, actually, since he'd already transferred his katra, um, uploaded all of his memory files and behavioral subroutines to B-4, and some of that programming was already starting to assert itself at the end of Nemesis, it really wouldn't take all that much for Data's files to assume control over B-4's neural net and, voila, Data's back.
