HAHAHAHA! ... that reeks of advertising hype rather than being a data based conclusion.Although a number of advanced SLRs offer spot-metering capability, the metering angle is directly related to the focal length of the camera lens in use. Every time the lens is changed, the effective spot-meter angle changes. With a normal lens in use, the spot-metering angle may be 15 degrees or more. A handheld 1-degree spot meter, on the other hand, allows the most selective measurement of distant subjects and small areas in complex scenes.
As I alluded, using a zoom lens on my DSLR allows for a very nice RANGE 'selections'.
Sekonic do make good meters though, so Chuck would give them some leniency.
