Compound Triggers - do they work (properly)?

Am I imagining this, or is there a *major* problem with compound triggers?
Consider this ...
[stbaldwin_at_opbld06 ~]$ cat sb1.sql
set serveroutput on size 1000000
create table sb_t(c1 varchar2(10));
create or replace trigger sb_t_ct01
for insert on sb_t
compound trigger
--
before statement is
begin
dbms_output.put_line('sb_t before statement (compound)');
end before statement;
end sb_t_ct01;
/
create or replace trigger sb_t_bi01
before insert on sb_t
begin
dbms_output.put_line('sb_t before statement (normal)');
end;
/
declare
procedure do_ins(i_c1 in varchar2) is
begin
insert into sb_t(c1) values (i_c1);
end;
begin
do_ins('aaa');
do_ins('bbb');
rollback;
end;
/
drop table sb_t;
As you can see, I create a 'normal' before insert statement level trigger, and a compound trigger that has only a before statement timing point.
I then execute a small anonymous block that calls an insert twice. I would expect to see four lines of output - 1 from each trigger * 2 executions.
Here's the output ...
[stbaldwin_at_opbld06 ~]$ sqlplus sb_test/sb_test

Table dropped.
As you can see, the compound trigger is only executed once.
Is this something stupid I'm doing or a possible bug?
Thanks,
Steve
