It was a humorous post, so he wasn't trying *too* hard to be accurate... The 
Epson gamut is considerably different in shape from the ColorMatch gamut, or 
Adobe RGB for that matter. The question is whether you want to fit ColorMatch 
almost entirely inside the Epson gamut, losing the areas in the Epson gamut 
tha ColorMatch misses (visualize a ColorMatch triangle fitting inside a 
roughly round Epson gamut; all the areas in the circle that are not also in 
the triangle are missed color opportunities) or do you wish to fit the Epson 
printer gamut inside the larger AdobeRGB space (picture the same rough 
circle, but with a bigger triange that almost encloses the entire circle; now 
you won't miss any printer colors, but you may have an occasional color that 
can't be printed accurately since its inside the AdobeRGB triangle, but 
outside the Epson printer gamut.  People say "gee, thats no good there are 
colors in my space I can't print", but in fact these same colors were still 
in your original image and can't be printed from ColorMatch either, plus lots 
of other colors ColorMatch loses as well. The choice is to lose them one 
place or another, plus perhaps to lose many otheres needlessly. But unless 
you are dealing with very bright, properly handled original images, you will 
not see the difference, since it will have been lost already.
