From that website:
The air is routed to the fan-cone or spinner via metal tubing, hollow static stator- and inlet guide-vanes in order to keep the temperature on the most ice-prone parts above freezing temperature. When being sucked into the engine again, the air also keeps the back side of the big front fan-blades free of ice.
Not on any high-bypass jet engine I've ever operated. Engine anti ice keeps the nacelles ice free but it certainly doesn't route air to to spinner or fan cone nor does it prevent fan blade icing. I suspect this may be but one of many inaccuracies on that site.
Edited to add I've just spotted a complete lack of understanding of the BA LAX-LHR 3 eng flight in there too.
