Bitcoin Source Code genesisOutputScript I am checking bitcoin source code to learn forking a coin better, 

in this link 

https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp

Line 52 has scratched my mind, what is that for? Should that be changed while forking a coin?

I know lines 124 and 125 are set after the first genesis block is mined, can someone explain me what line 52 does, and how it affects the blockchain?
You can use this code for genesis block:
