TestFlight invitations

Reported a bug to Apple that I never get TestFlight invitation email or see my app in TestFlight app.

They replied back:

Once an e-mail is added to an app in iTunes Connect for TestFlight, that e-mail cannot be re-used for that app in TestFlight unless the tester is removed and re-added.

Why cant they just notify user that you cant receive invitation because you are already part of another program?
