Kunzite didn't yell out refresh in the 90's anime because he knew his life with zoisite was a lie. He couldn't bear the thought of their love being a lie. Kunzite was already heartbroken so bringing back his memories would have traumatized him. So he would rather die with the lie.
Imo, the anime is at best vague about how the Shittennou fit into the Silver Millennium. I know, until I watched the CD game I simply presumed they (and probably Beryl) were not human at all and were simply humanoid creatures who shared a common origin with the Youma, Metalia, etc
