I think it is always a bit of a caution to have an active giving advice on topics which they may not have much experience with - i.e. recommendations. The fact of the matter is, in NPC sororities, it is the alumnae who are responsible for almost every aspect of recommendations until they reach the hands of the actives. The average active (there are exceptions, I am sure) don't really need to or have the practical knowledge of all the behind the scenes actions alumnae take with recs.
She should focus her advice on what she personally has experience with, and then only if it does not conflict with NPC UAs.
Just because you are in a sorority does not mean you are qualified as an "expert" in recruitment matters.
