You have a passport. One day you need it for something and whoa! It’s “lost.” You apply for (and receive) a replacement, and there you are: Two passports. Now, the new one declares the old one void. But there is no way the old one can note that.

Don't they assign a new number for the new passport, making the old one useless (other than as a souvenir)?

I would assume so. But I highly doubt anybody cross-references the numbers at the borders. I don't think he was pulling anything, I was just suggesting how two passports could legitimately exist.
