It's not wrong, it's just potentially misleading.

> Your browser fingerprint appears to be unique among the 251,543 tested in the past 45 days.

It only counts against those other people who visited panopticlick, and that in the last 45 days. That's explicitly stated, but hidden in the click-through for details section.

There are also things it can't detect, such as the existence of the Cookie Auto-Delete extension. So it thinks cookies are enabled and can be used for tracking, but in reality they get deleted whenever I close a tab (and links to new domains get opened in new tabs). Or user-agent randomization, which will make your fingerprint more unique but less useful for tracking.
