How is this **NOT** erroring out with ORA-00904?

Question

SQL> select * from v$version;

SQL> SELECT order_line_id FROM t1
  2  /
SELECT order_line_id FROM t1
ERROR at line 1:
ORA-00904: "ORDER_LINE_ID": invalid identifier
SQL> SELECT * FROM t2 WHERE order_line_id IN (SELECT order_line_id FROM t1);
no rows selected
SQL>If it's in the manual, please point that to me. I was fully expecting it to give me the error the second time around.
PS:
This was the same in 11gR2 Enterprise Edition too.
