One reason I posted this is to bring attention to the use of the word "may" as opposed to "shall." 2-27-2 uses the word "may," meaning, (or at least appearing to mean), that the neutral zone is not always expanded. I agree with JimS that the expanded neutral zone is a "blocking" phenomenon. I'm still looking for clarification about other situations, (other than not expanding into the end zone), where the neutral zone would not be expanded.
If there aren't any other situations, and the "may" is simply in the rule because line blocking sometimes does not extend past the defensive line of scrimmage, then I'd like confirmation of that. Is that the case?
