In the Ice World we saw that Amaterasu is the Nature Transformation, while Kagutsuchi is the Shape Manipulation. So instead of creating flames and then using shape manipulation on it. Blaze Release is more like using both at the same time to create flames that already has shape manipulation applied to it.
