Klinefelter male calicos are indeed always infertile, so all the fertile male calicos are chimeristic in nature. That means they have their colouring from two originally separate fertilized embryos, but the sperm of the chimera kitty comes just from one, and as such is genetically either that of a black or an orange cat.
There is for some reason a myth about fertile male calicos being incredibly valuable. I think I've even seen it mentioned on /an/ once. Obviously it isn't true. While a fertile male calico is a rare curiosity, it doesn't have any unusual genetic quirk for creating more fertile calico males, which is probably the only reason anyone would want to pay lots and lots of money for them.
