Looking at the original version of the film right now, and Orga's original roar was identical to Cretaceous King Ghidorah from Rebirth of Mothra 3. I guess the Americans wanted to be as original as possible and opted for a new roar that was unique to the creature. Like how the MUTOs were unique to the new Godzilla film.
