“Want to buy the worldwide license to my two-factor-authentication patent? (13 countries incl. US & China) Email: [e-mail],” he concludes.

I guess he means he will license his patents more than one company. In contrast, if he sells all the patent rights, he can't sell them to anyone else and those who want to acquire a license should negotiate with the buyer.
