With NPC sororities, potential members sign up for recruitment and are encouraged to keep an open mind---they aren't "rushing" ABC or XYZ, they are going through recruitment looking at every chapter. Potential members want to get a recommendation for each sorority on her campus. An ABC alum may only write a rec for ABC and not for XYZ.

With NPHC sororities, interested women research the groups themselves, and then choose one to pursue. If things don't work out with her chosen group, she does not pursue another group. As far as the recommendation process is concerned, I do not know how the NPHC works.
