It would make sense though - instead of a new remix, the 1985 release had its audio digitally remastered from an existing mix.
Then again this David C. Fein seems to have credentials (despite the inaccuracies about the ISR laserdisc) - it looks like he now works with Michael Matessino (the guy who gave us the list of ESP 70mm print differences) at a DVD production company called Sharpline Arts.
