This is the reply I posted in response to the question from Jarski, which was right below the post you quoted anglebaby87...
That's just an artifact of how all coin wallets handle transactions -- its called
Change. Coin transactions consist of inputs and outputs; all coins in an input must be accounted for in an output. You can force transactions to come in and out of a single address using raw transactions, which is what we did initially to send the premine from the original premine wallet address to the current wallet; however, that is a very low-level process which is potentially prone to human error.
It is much better to just use the normal wallet for sending coins around than to rely on raw transactions, since even for experienced developers there is always a risk of human error. Of course, the coins are still trackable via the blockchain under any change addresses that the wallet uses.
Here's two screenshots of the wallet:


Note that the premine balance has been reduced from then until now by way of payments, which we detail in a post every day. Here's the
current premine balance with 23587.999948 MAST.
