> I thought everyone knew the person that reads the code can only describe it to someone else who writes the new code. Having the same party do it would make it a copy, if the purpose and construction is the same. The same party can do it and not have it count as a copy, but it could be a copy if the party was not careful. So a company that wants to avoid potentially being sued will not allow one party to do both. So jimmaswell is correct to my understanding but a company may want extra legal armor/padding.
