They are "potential" in that person A does not know that person B is 
actual fellow member of the ingroup.

Thus, for person B, person B is an actual member of the ingroup, and 
person A is a potential member, but for person A, person B is a 
potential member of the ingroup and person A is a potential member.


The problem is that we want person A to be able to find out that person 
B is a member of the ingroup, without person C finding out that person B 
is a member of the ingroup.
