That does not seems to be right explanation at all, if it is realy true, given the fact that for example for moleman they changed the mechanics to match the text, yet here they change the text to match the mechanics? That seems fair for sure
The core has always been to fix what's broken to match what's intended. Hyperion had at the time those buffs and was supposed to increase their duration. But that didn't specify that. So they updated it. Moleman is very obviously a function error since you only got to keep the true strike if you played a specific way and all others would lead to losing it.
