I have come to the same conclusion, with a revision C. I have also tried it with a 630nm and a 532nm laser diode and was unable to notice a significant difference in the high-resolution mode.
My observations with regard to a laser, are that it shows that the effective spectral resolution is better by about 60% (ie. if you look at the half power width on a red laser, it drops from about 19nm to 8nm width). See <http://www.argyllcms.com/doc/HiResLaser.jpg> Graeme Gill.
