New Link Syntax is weird

So I'm familiar with

  • HTML
    <a href="url">link text</a>
  • BB Code
    [url=url]link text[/url]
  • MediaWiki
    [[link text][url]] link syntax
But the current Verge syntax for links in comments
"link text":url
is really weird. I tried highlighting some text and using the "insert a link" button and I was super confused.
