[exim] ratelimit question

Hello. I'm using exim to ratelimit local not_smtp messages in this acl:

acl_check_not_smtp:
  deny  ratelimit = 2000 / 1h / strict / $sender_ident
        message   = You can only send $sender_rate_limit per
$sender_rate_period
        log_message = "RATE: $sender_rate/$sender_rate_period (max
$sender_rate_limit) $sender_ident"

To check this acl i wrote test case:

for x in `echo {1..2000}`;do echo test | /usr/sbin/sendmail -v
fg3758937453749573897539dlgdkfjgkldfjgkldjgkldjglkdjgkljfklgjdklgjdkljkgldjgldjgkljfdlfdgdfgdfgd@???; done

(address not exists - this is right).

After some time i get error says that my ratelimit exceded. 3680 of
2000. How can this do? May be exim counting bounces?
I'm not completely understand, why i can't send 2000 messages..
Please help me...
