Organic gardening implies adding enormous amounts of organic matter to the soil, etc., etc. Adding sulphur to the soil would produce important amounts of sulphidric that would poison and kill all sorts of plants. Hence this advice comes from practical experience. As you say powdered sulphur DOES lower the pH but in a more stable, less organic soils.
