Title authors rarely pick "title, subtitle, summary", editors do.

It makes sense that the title and summary would restate the same thing - the main point of the article.

And what you considered as the first paragraph (in calling out "first two paragraphs") is in fact what's called a pull-out, an extract of the article that's also in the body (a part that sums something up, a quote, etc).

Sometimes the reason for such duplication is that those serve different purposes in different views (main post page vs listing vs RSS feed vs archive vs picture grid article list vs the mobile "responsive" layout, etc).

The problem here is that the layout is badly designed: the summary could be ommited, and the pull-out shouldn't appear on top of the article, with minimal distinction (just larger type and italics) but preferably in a box somewhere further down for those skimming the post.
