Dynamic mutation, right?  I hadn't considered something like that, but 
it makes much more sense that my propositions.  However, it still 
seems that there would be that a pesky recessive gene lurking on the 
other chromosome (I could be wrong, but it seems unlikely that both 
genes would reach the pivotal number of repeats at the same time).
