You're right about that ...

... but this does not follow, because it's a poor analogy.  "Member of"
means "these role(s) have been GRANT'ed to pg_monitor".

As a more typical use-case, there might be a role "sysadmins" that holds
assorted privileges, and then certain individual users are granted that
role.  Nobody would quibble with seeing

             List of roles
 Role name |  Attributes  |  Member of
-----------+--------------+-------------
 bob       |              | {sysadmins}
 joe       |              | {sysadmins}
 sysadmins | Cannot login | {}

and I think most would agree that titling the column "Members" would
be backwards.
