IPN need not be enabled ?

- tried a vanilla drupal 6.20 + ubercart 2.4 and created a new business test account on the sandbox.
- updated the paypal website payment standard settings on the ubercart site and placed a test order.
- logged into paypal sandbox with the personal account and made a payment.
- the payment went through and when see the watchdog entries saw the detailed ipn entries.

would this mean that the IPN settings in the Paypal Business Test Account (Profile -> IPN) is no longer relevant ?
