I could be wrong, but I believe it's the other way around. My understanding:
For vanity, tweets with links to 'twitter.com/blahblahblah' are visually edited to show 'x.com/blahblahblah', but the backend still sends the user to the original twitter URL.
So someone could potentially link to a malicious site hosted on 'netflitwitter.com' or something, and the filter would make the link look like 'netflix.com' while still directing the user to the malicious site.

Wasn't it cosmetic? At least, that's how I understood it.
The UI basically did `sed 's/twitter\.com$/x.com/g'` showing e.g. fedex[.]com as link preview while the link actually went to fedetwitter[.]com.
