I just retested the functionality.
I manually sent an email to a non-existent email account through my business domain. I received an undeliverable response. In WP, I set the email address for a test user to the same non-existent email account. I set the Bounce Override Email to one of my alternate email accounts. I used the plug in to send an email to the test user. I never received a response at the account for the Bounce Override Email. I turned Debug Mode on in the plug in and attempted to sent an email to the test user again.
Here is the wp_mail() Debug response:
Temp Account <[email protected]>
Test 3.4
<html><head><title>Test 3.4</title></head><body><p>This is a test to determine if this email is deliverable to this account. It should be bounced to [email protected].</p>
<h5 style="border-top: 1px solid #eee;"></h5></body></html>

Here is the PHPMailer Debug response:
