Interestingly they do not cite calculating a signed distance to the surface of the shape as an approach to doing AA, as described in the Valve paper [1]. I suppose this is more targeted at offline baking, but given they're suggesting iterating every curve at every pixel, I'm not sure why you wouldn't.
