My mistake, re-reading it I find: "Registered variables are valid on the host the remainder of the playbook run, which is the same as the lifetime of "facts" in Ansible. Effectively registered variables are just like facts." However, the lifetime of "facts" is not defined. Maybe it should be? As I understand it "facts" in the sense of system attributes are persistent between runs, but Ansibles' internal store of collected "facts" endure for the play (or playbook?), but not between runs. The difference is muddied since (also, as I understand it) the internal "facts" data structure, or some portion of it, gets re-created at the start of each play by the 'setup' module.
