Borders, Citizenship and Immigration Bill [HL]

I ask this only to test whether I have understood the text of the Bill correctly. I am looking at the passage that says: "““This section applies to … an enactment passed or made before the end of the session in which this Act is passed, and … an instrument or document issued before the passing of this Act””." Those seem to me to be helpfully exclusive statements. The second, relating to Acts already passed, is straightforward. The Bill is then saying that the only other kind of enactment that could apply would be one that, because this is a running issue, may be passed after we have concluded the business of this Bill. In that case, the word ““only”” would not be needed, because it would exclude any Bill or enactment subsequently. If I have not understood that correctly, I have no doubt that the Minister will tell me.
