The ideal height of the grout line would be just at or slightly below the micro-bevel which looks like a light colored line around the Moss tile. Normally, you wouldn't want the grout line all the way to the top surface of the tile, but that is a "personal taste" question.
From your description, it sounds like your application is normal.
