No, pointiness with Eevee doesn’t work. But I saw the baking was also done with cycles.
The advantage would be to have more control over the texture map creation if you are using cycles instead of dirty vertices method.
Anyway, I’ve learned another method of creating cavity and edge maps, besides pointiness, AO and https://cgcookie.com/tutorial/better-edge-and-cavity-masking-with-cycles?utm_source=blender-nation&utm_campaign=tutorial&utm_content=better-edge-and-cavity-masking-with-cycles .
