The Curious Case of NefarianZoneDeath2.wav

Sometimes when I really want to kill some time I go through the data files using the MPQ editor and go through all the various sound files. Today in patch.mpq I found NefarianZoneDeath2.wave under Sound\Creature\Patch 1.8_VO_Lines. Alternatively you can listen to it here - http://www.wowhead.com/sound=8469/vo-nefarianzonedeath2
My question is did people in the SG/BS zones hear this whenever Nef was killed in Vanilla? Or was it unused?
