If I can draw a parallel, it would be exactly the same principle as interceding, in the legislation, a section 52.1. You already have a section. You're amending a section. Obviously, as part of the amendment that you will add into the legislation, you're called to add section point-something. Again, it has no bearing on the substance. It's purely a drafting technique.
