That was the point - that with HID bulbs in a housing designed for halogen (or whatever), it LOOKS brighter, especially immediately in front of the bike, but there's less light down the road. Result: your pupils shut down and you actually see less.
Take it for what it's worth. I thought the article made some good points about things to consider. Ya always gotta go with what you think best, though.

I can tell you, and this is an undisputable fact, experienced on my own bike, and I'm not merely trying to justify the $400 for the new lights.
I could not see CHIT in front of my bike with the stock headlight. Granted, it was not aimed high enough, but the difference with HID is mind-blowing. Maybe if I didn't adjust the headlamp, and left it pointing at the ground 30 feet in front of the bike, would their analysis make sense, but there is absolutely no comparison between the stock halogen and HID lights.
Looking at Travis' pictures CLEARLY shows the extra range you get with the HID's. I'll stop here, because Travis' pictures are worth thousands of words.
Lo Halogen (Where are the Trees?)

Lo HID (There they are)

Hi Halogen (Barely see the trees here)

Hi HID (Damn! Them some BIG trees)

Granted, raising the stock headlight will yield an improvement, but it won't get you all the way there.
School's out.
