Why the container components has lot of markup ?

from article by Abramov https://medium.com/@dan_abramov/smart-and-dumb-components-7ca2f9a7c7d0#.gqy6bmbp3

"May contain both presentational and container components*\* inside but usually don’t have any DOM markup of their own except for some wrapping divs, and never have any styles."

But in this source code all the container components has lot of DOM markup. If I'm not wrong the purpose of container component is to provide the behavior of the component but not presentation.
