It's alluding to the fact that you arbitrarily chose to divide G by 2.
Stop trolling. There is almost nothing arbitrary about 1/2; it's the simplest fraction.
I also find it intriguing that the x-coordinate of 1/2 * G, while large in absolute terms,
is so relatively minute. If the people responsible for picking G ever come forward to
explain their choice, I'm sure it will explain the 1 in 10^26 odds that this choice would happen at random.
