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.
