I can confirm in testing this function that you are correct.  I have
fixed the documentation as you suggested.  Thanks.

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

drop function bb();
create function bb () returns integer as 'declare i integer;
begin
for i in reverse 10..1 LOOP
insert into aa values (i); 
END LOOP;
return 0;
end'
LANGUAGE 'plpgsql';
