That is not written in the page that you showed. Besides in the page that I linked, it is written in the "Bureaucrats" section that

They have the ability to promote and revoke rollback, Content Moderator, and administrator rights as well as appointing new bureaucrats. While they cannot directly remove another user's bureaucrat status, they can remove their own.

Therefore it is clear that they can revoke admin.

I don't vote as my suggestion on the correction is ignored.
