Replication Autogenerated Procs - Interesting ;2 Notation

I was looking to modify how the INSERT happens with regards to replication only to find my solution in the proc itself. When I edit the proc this is what I am displayed in SQL QA or EM:

SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO

Is the second version listed at the bottom like a comment or can it actually get called? I am going to script out all of these procs and save them, and then remove the first version (listed at the top) and the use the second version since it does what I need. I just thought it was interesting to see two stored procedures in a single definition, never seen the "PROC_NAME";2 notation, have you? If so please tell me what it does, is it just a way to create a second version of the procedure in a comment type fashion or is it used another way?
