Shared roster presence

I've installed Openfire 3.9.3 and enabled shared roster. In admin interface I see what all contacts in my roster have 'both' presence, but when I get 'Iq' request I see subscription='to'.

<!-- 13:50:06.866 IN (::xmpp::2, andrey@***/work) -->

<iq type='set'

id='889-501707392'

to='andrey@***/work'>

  <query xmlns='jabber:iq:roster'>

  <item jid='alex@***'

name='Alex'

subscription='to'>

  <group>support</group>

  </item>

  </query>

</iq>

Could you advise how to determine right subscription.
