Twitter Cards | Twitter Developers
"You'll notice that Twitter card tags look similar to OpenGraph tags, and that's because they are based on the same conventions as the Open Graph protocol. If you're already using OpenGraph to describe data on your page, it’s easy to generate a Twitter card without duplicating your tags and data. When the Twitter card processor looks for tags on your page, it first checks for the Twitter property, and if not present, falls back to the supported Open Graph property. This allows for both to be defined on the page independently, and minimizes the amount of duplicate markup required to describe your content and experience.

Note that while Open Graph requires specifying the "og:" prefix via <html prefix="og:">, no such markup is required for Twitter cards or the "twitter:" prefix. OpenGraph also specifies the use of property and content attributes for markup (<meta property="og:image" content=""/>) while Twitter cards use name and value. Twitter's parser will fall back to using property and content, so there is no need to modify existing OpenGraph markup if it already exists in your page."

<-- there's the hook/reason, ladies and gentlemen
