valve clearance - hydraulic lifters

Hi.
Someone please make me understand how the engines with hydraulic lifters are valve tuned/adjusted! I was reading from an article that explains as quoted below

"...Instead of setting the valve lash to 0.006", the hydraulic adjusting screw makes contact with the valve stem and you turn the screw a couple turns and you're finished. No feeler gauges are required. The engine pumps the lifter full of oil and as the clearances of the engine parts change due to heating expansion, the lifter adjusts automatically. Besides fewer required valve adjustments it means less startup wear on the valve train compared to a solid lifter engine because the engine is adjusted at all temperatures not just when the engine is hot..."

Please, anyone with this engine information on the matter, confirm this as well as shade as much light.

This seems to be an awesome engneering...
Thanks.
