The diagram shows the logical links between the task and the two coroutines, it
does not describe exactly how things work internally. For example, the sleep
coroutine creates an internal future which uses
:meth:`BaseEventLoop.call_later` to wake up the task in 1 second.

when it gets a coroutine instead of a task.
