That is an overly simplistic view of incident metering v reflective metering. I wouldn't even deign to call it an "article," although, probably by definition, it is. One paragraph does not an article make IMO, though.
Digging further into the site we come across this page: http://www.sekonic.com/IncidentVsReflect.html which offers a little more, and more valuable, information. Shel > [Original Message] > From: Graywolf > The Sekonic website has an article about incident light metering http://www.sekonic.com/BenefitsOfIncident.html that is very useful in understanding exposure even if you do not use an incident meter. I do however recommend incident meters for general photography. they provide for very consist exposures, because they measure the light level rather than the brightness of the object being photographed.
