You could easily notice this same thing in the early days of trans fat removal from product: it was common to see labels and nutrition panels touting "0g trans fats" but have partially hydrogenated oils pretty high up the ingredients list: again mostly on the back of a small serving size. I suppose it's still around in some product categories.

I don't recall ever seeing Tic Tacs actually claim "sugar free," though. "Zero grams" is allowed and most people read it the same way, while "sugar free" actually has some more requirements to be able to use.
