THIS!

Tbh, it's kinda annoying how almost everyone adopted headcanon that Sans remembers literally everything as canon. He even states during his battle that everything might get reset WITHOUT HIM REMEMBERING. If anyone remembers the most from resets, it's Flowey since he act drastically different and calls us out if we reset a certain route.

Sans gets a little memory from non-true resets, but literally every other major character does. The only difference is Sans is AWARE ABOUT EXISTENCE OF RESETS and of course he'll give those pieces of memory more importance. But that still doesn't mean he remembers literally everything.
