Comment (by OlegSerov):

 Let's assume that you are right in the fact that && should somehow work
 differently from "ST_Intersects".

 But there is still an issue with ST_Intersection:
 {{{
 SELECT ST_Intersection(ST_GeogFromText('POLYGON((-116.614 61.7534,-109.804
 61.7534,-109.804 57.5029,-116.614 57.5029,-116.614 61.7534))'),
  (ST_GeogFromText(' POLYGON((172.347846 71.441059,-173.233993

  71.441059))')));
