The legislation requires you to ask consent for non-essential (ie. tracking) cookies. So unless they put a tracking cookie on their site the behaviour is correct, and that text is simply incorrect.
That's my bad for not quoting further, the very next paragraph is:
> First-party cookies are set by 1Password. They help calculate things like page views and visitors to the website. Third-party cookies are set by 1Password affiliates for commission and advertising purposes.

They make it clear that they know consent is required, that they absolutely fall into that category, and then don't ask.
