When you combine simple or negated simple conditions in a consecutive
  sequence, you can abbreviate any of the relation conditions except
  the first.  You can do this by either:

    1)  Omitting the subject of the relation condition
    2)  Omitting both the subject and the relational operator of the
        condition

  A relation condition in the consecutive sequence must contain a
  subject (or subject and relational operator) that is common with the
  preceding relation condition.  There must be no parentheses in the
  consecutive sequence.

  Format -

  relation-condition { { AND } [NOT] [relational-operator] object } ...
                     { { OR  }                                    }
