Greg,

The shunts cause the manetic flux of the core to bypass the 
secondary to a degree.  It's as if the secondary was physically
removed to a degree (in a sense).  If you did remove the secondary
completely, obviously the transformer would draw only its 
magnetizing current.  So here you have an in-between situation,
some flux gets to the secondary, but not all.  This limits the
secondary's ability to draw current.  The more current the 
secondary tries to draw, the more flux is shunted, which tends
to limit the current.
