Not sure I agree - most fonts are cached (as pixels) at a few offsets, so the ability to place a character is constrained by 1-pixel increments (or 1/3-pixel increments in the case of ClearType). A true vector placement of each character gives you the ability to show type at any subpixel offset and then anti-alias, and I think there's a good chance they're doing this.
