does membership plugin require global tables?

hello,
The installation instruction to not mention if you need to create global tables for this plugin.
I don't see a blog id reference there so I am assuming it need global tables entries.
Is that correct?

Thanks
Joe

Looking at

CREATE TABLE 'wp_1_membership_levels' (
  'id' bigint(20) NOT NULL auto_increment,
  'level_title' varchar(250) default NULL,
  'level_slug' varchar(250) default NULL,
  'level_active' int(11) default '0',
  'level_count' bigint(20) default '0',
  PRIMARY KEY  ('id')
);

CREATE TABLE 'wp_1_membership_relationships' (
  'rel_id' bigint(20) NOT NULL auto_increment,
  'user_id' bigint(20) default '0',
  'sub_id' bigint(20) default '0',
  'level_id' bigint(20) default '0',
  'startdate' datetime default NULL,
  PRIMARY KEY  ('rel_id')
);

CREATE TABLE 'wp_1_membership_rules' (
  'level_id' bigint(20) NOT NULL default '0',
  'rule_ive' varchar(20) NOT NULL default '',
  'rule_area' varchar(20) NOT NULL default '',
  'rule_value' text,
  'rule_order' int(11) default '0',
  PRIMARY KEY  ('level_id','rule_ive','rule_area'),
  KEY 'rule_area' ('rule_area'),
  KEY 'rule_ive' ('rule_ive')
);

CREATE TABLE 'wp_1_subscriptions' (
  'id' bigint(20) NOT NULL auto_increment,
  'sub_name' varchar(200) default NULL,
  'sub_active' int(11) default '0',
  'sub_public' int(11) default '0',
  'sub_count' bigint(20) default '0',
  PRIMARY KEY  ('id')
);

CREATE TABLE 'wp_1_membership_relationships' (
