The new certificate of birth shall show the true or probable foreign country of birth, and that the certificate is not evidence of United States citizenship for the child

A foreign birth, if no documents are available, means they have to "guess" or assume the facts themselves. That's why a foreign certificate does not constitute legal natural born citizenship, or any citizenship for that matter.

A foreign certificate simply agrees the person was indeed born some where at some time.

Good point-even the COLB means nothing without the long form.

The COLB doesn't prove you are a citizen.
