Rixa is right, especially some autoboot code for example started to load from the end of the rom area (writing goes to ram instead) and when the address of the next byte to be written wrapped to 0 from 0xffff the rom could be changed to ram suddenly with the custom code pre-loaded already instead of the rom code.
And this is just one of the many inventive ways of autostarting software on C64
The point is, anything that is not identical code at least in the IO routines is a waste of time.
