Even the change in the line is perfectly consistent with Sans having only a vague sensation of what happened in another timeline, just as Toriel remembers your preference for cinnamon or butterscotch. He simply knows that that vague sensation isn't a random occurrence. Good point, but Sans can actually count how many times you've died, ''exactly. ''I don't think he's getting that from the expression on your face.

Then why the line at all?

He already knows you are the one manipulating the timelines. In other words, he knows that you know how many times you've died. There's no need to trick the player with this "face reading" if he actually remembers. He could just say "well, that's one death," "that's two deaths," etc., etc.

It's also worthwhile to note that he only counts to 12, and then stops. And as he gets closer to twelve his ability to tell how many times you've died gets fuzzier, and in fact when he hits eleven he says "well, give or take. there's nuance to this stuff." But if he actually remembers, then he's just counting, to which there isn't really any nuance.
