ICANN does not allow the expiration date on a domain registration to be more than 10 years in the future. Unless they made some special deal with ICANN, what Wordpress is almost certainly doing is the same thing Network Solutions does (or did? [1]) for their 100 year registration product. Register it for 10 years, and then add more years every so often over the next 100 years to keep pushing the expiration date out (but never farther out than 10 years) until the expiration date reaches 100 years from the start. [1] I'm not sure Network Solutions still offers 100 years. I just checked and it only offered up to 10 years for the domain itself. It offered up to 100 years on some of their add-ons such as their private registration option.
