This example has a metafield saved on it containing the handle to a few articles. The template code loops over those handles and shows the article titles below. You'll see that the articles used are not from the same blog, nor are we looping over every article in a blog.
See the main post for more info on this.
The metafield value we're using for this example is this:
news/my-new-article-title,press/example-press-article-2,press/example-press-article-7
My new Article title
Example Press Article 2
Example Press Article 7
