Dual Memberships

[Miriverite]

I know this thread is old a hell, but (from the Gamma Sigma Sigma site):

The College Pan-Hellenic is composed of members of all the eligible sororities and fraternities on its campus. The delegates from chapters of these sororities and fraternities form the College Pan-Hellenic Council, which is responsible for local Pan-Hellenic operation in accordance with National policies and procedures.
Gamma Sigma Sigma’s prohibits affiliation with the National Pan-Hellenic Conference. Pan-Hellenic membership involves the question of adherence to the basic principles on which Gamma Sigma Sigma has been founded. Although some chapters may be non-voting members of their local Pan-Hellenic Council in order to meet student organization requirements for sororities, no GSS chapter may become a regular member of the local Pan-Hellenic Council.

First off, are they referring to both the NPC -and- the NPHC? The way they have it written implies NPHC, but from context I think they're referring to any national Panhellenic group, whether NPC or NPHC. In addition - correct me if I'm wrong - the second paragraph implies that a member of GSS can also be part of their local Panhel (i.e. part of a Panhellenic sorority), but the GSS chapter is prohibited from joining the college's Panhellenic Council as an active, voting body...?
