Thanks for such a detailed explanation!

I use stock blog_example without modifications and only its "index" action, 
which is:

public function indexAction() {
	$this->view->assign('blogs', $this->blogRepository->findAll());
}

Does that mean that current() PHP function is called on this object inside 
Extbase?
