As I understand it, half of the key that decrypts the phone is stored on the chip itself and cannot be read. When you enter in a correct password on the lock screen, it is added to this hardware key and the combined key is then able to decrypt the phone. If you move the contents of the hard drive to another iPhone, the key on that phone will be different and thus can't decrypt the drive. Its like 2 phase authentication on your Gmail account and you are being sent the wrong codes. Check out this article for more information.
