How do cookies on Twitter give me "safer experience"?

[Georgi Guninski]

With javascript and cookies disabled, go to https://twitter.com/

Orange CSS shit which can't be closed with the "X" suggests:

> Cookies help personalize Twitter content ... and provide you with a
> better, faster, safer Twitter experience. By using our services, you
> agree to our Cookie Use.

Me fails to see how browsing Twitter with cookies enabled makes me
any any safer.

How so?
