I don't think it's valid to add the triggered updated rows:

1> select * from a select * from b
2> go
 a
 -----------
           1
           1
           2
           2

(4 rows affected)
 b
 -----------
           1
           2

(2 rows affected)
1> create trigger atrig on a for insert 
        as insert b select * from inserted
2> go
1> insert a values (3) select * from a select * from b
2> go
(1 row affected)
 a
 -----------
           1
           1
           2
           2
           3

(5 rows affected)
 b
 -----------
           1
           2
           3

(3 rows affected)

Note "1 row affected" on the insert.  Anything else would be highly 
misleading.  

Feel free to ignore me if this isn't material to the question.
