The issue as I have now come to understand it is simply a doubling of the total amount. The percentage of each stake remains unchanged (I.e. 1MM NEM is now 2MM NEM).
The genesis of this change being the apparent Chinese superstition regarding the number "4".
It was Eadeqa who pointed out that the 4 was something copied off Litecoin. Litecoin isn't even relevant anymore (Ripple has a bigger capitalization).
