As it says towards the end of the article, this is a form of continuous fermentation. Flowing the wort past the yeast is what makes for speed. Those of you who have a stirrer for your starters have seen the benefits of keeping the wort moving. If we, as homebrewers, made really big stir plates, our fermentation times would drop to less than a day.
Some lagers are finished by forcing them through yeast beds. This cuts the diacetyl "rest" to minutes.
