The page says that as of today (2020-01-01) the status is active. The wording is confusing.

There seems to be a weird bug on the Google Patents site. I've noticed that the expiration date of a patent is always the day I visit the site, even for patents I know expired a while ago. This may be something like that.

It's not wrong but it is confusing – it's showing you what its current status is, which should be shown somewhere else than in the timeline.

Ah, thanks. As in Expired (date). Where date is every day from the day it expires until forever. Not Expired on date, but currently expired. Makes sense now.
