Mysterious Join Results...!

Oracle 9.2.0.2 RHEL 4 Linux (Itanium).

I have picked up on a subtle difference in the new 9i Join syntax. It appears that there are 2 forms of the join command which seem logically the same, but return different results:

In the 2 statements below, the only difference is that I have changed the keywork 'AND' to 'WHERE' on line 3....

Why does this return different results..? It looks as if the additional filter (d.loc='DALLAS') is being applied at different times.

  1 select e.ename, d.deptno from emp e right outer join dept d on   2 e.deptno = d.deptno
  3* and d.loc = 'DALLAS'
SQL> /

ENAME        DEPTNO


----------           ----------

                        10
SMITH              20
JONES             20
SCOTT             20
