If this is who I think it is, I don't think it works. I had this enabled before seeing the scene where she dies, but she still died and is still dead after leaving that place. Unless she comes back further down the line?
Rather than assuming the option doesn't work, you should instead contemplate if your pre-conceived notions have led you astray on what the option actually does.
Vehek is right, it restores the Bugenhagen scene. My greatest character flaw is being intentionally misleading for my own amusement.
Anyway,
Version 1.21 is out now (yes even on the google drive). Thanks to the OpenFF7R discord we got ahold of a proper script dump for Rebirth, and meticulously compared it with OG's for overlap. SAC's been updated accordingly, as well as adding some overlap with Remake we missed the first time. This should be the final major revision to the script until Remake part 3 comes around, so SAC is now for all intents and purposes "complete" (not that it wasn't already more or less in a complete since 1.0).
Updates from here will be the usual bug fixes, and pursuing a few extras I haven't yet been able to add.
