I am not sure what part you are talking about. Shyster is the one that pointed out to me where it was.
I over simplified the concept in listing it here, but I also linked to the actual laws so the conditions could be read. Yet it still makes the separation (conditionally) required. The other place it is listed is excepted by the license with a CPL.
You are correct that the thread is not about drinking, it is about carrying. One of the conditions of carrying is the subjects sobriety, therefore it can't be totally be ignored.
