It's mentioned at the end of the link that an older tree has since been recorded.

Note the photo and think about counting 5000 age rings on a pencil (roughly the situation with a core) and I think it becomes clear that 'recorded' is an important part of it.

Definitely. Thats how I I started recognizing the older trees from the sequoias I believe which are one of the oldest species of trees out there.
