Does CCDE written recertify your CCIE?

Hi Expert,

Sorry if my question is too general. But I have blur in Cisco explanation
here in: http://www.cisco.com/web/learning/le3/ccie/recert/index.html

It says: "*To maintain active status, every 24 months CCIEs are required to
pass one of the following: any CCIE written exam of their choosing, a CCIE
lab exam, or either of the CCDE exams.*"

Does it means CCDE written exam? Expert please validate.

Thanks.
