I hope he will give us an actual example from his work. But meanwhile, here's a classic example:
The Donau is a river. On this river is a steamship (Dampfshiff): Donaudampfschiff
This ship is part of an organisation (Gesellschaft) that manages cruises (Fahrt): Donaudampfschifffahrtsgesellschaft
The ship has a captain (Kapitän) who has a cap (Mütze): Donaudampfschifffahrtsgesellschaftskapitänsmütze
On this cap is a button (Knopf): Donaudampfschifffahrtsgesellschaftskapitänsmützenknopf
You could extend this example: The button is colored with a special paint (Farbe), which is produced in a factory (Fabrik): Donaudampfschifffahrtsgesellschaftskapitänsmützenknopffarbenfabrik
And the factory has an entry gate (Eingangstor): Donaudampfschifffahrtsgesellschaftskapitänsmützenknopffarbenfabrikeingangstor
In English, this would be a huge sentence, all in reverse order: The entry gate of the factory that produces the color for the button on the captain's cap of the ship belonging to the cruise organization on the Donau.
The German is a lot more compact, if sometimes hard to parse :-)
