Uh, the text says:

   NOINHERIT
   These clauses determine whether a role “inherits” the
   privileges of roles it is a member of. A role with the INHERIT
   attribute can automatically use whatever database privileges
   have been granted to all roles it is directly or indirectly
   a member of. Without INHERIT, membership in another role
   only grants the ability to SET ROLE to that other role; the
   privileges of the other role are only available after having
   done so. If not specified, INHERIT is the default.

The controls whether the role being created inherits anything, not how
role members behave.

Well, what happens is the the "backup_label" file is created in the WAL
directory and that file gets backed up during the file system backup. 
That file will appear in the backup, like in the tar file.  Can that
text be improved?

Okay, makes sense.  Here is an updated patch.
