he probably doesn't want other people to update and post his cheats using
ASM Cheats Updater
when an update is out, he wants to do it by himself
also, this leaked version might not be the final retail version
It's most likely his way to "sig" or stop people from easily reversing his cheats..
He just.. uses a standard offset, then subtracts it from code address, and does it on the fly with the code to inject his asm.
