Can we use an attribute for all the user roles even after we wrote xpath in entity security as for curent user

We have two user roles in our application. One user wil have admin rights so no need of xpath in entity security.
for another i have used xpath as curent user because we need to display only related data of logged in user.

but from an entity i need to use a reference set dropdown based attribute need to be  the same  for both the user.

Thanks in advance
