They are exactly identical, however, when the brain starts up each one would start gathering it's own data.
For example, person A would be standing on the left and person B would be on the right. Now the first thing person A sees is a television, and the first thing that person B sees it a radio. Person A would see person B to his left. Person B would see person A to his right. (Don't get technical with this part, it's the difference in experience that matters) As you can see they have already at this point, gathered different information. The data stored is not the same anymore. It's like with identical twins, they are both the same, but they have different experiences. To further support that, let's say person A and person B has not differed yet. They both go to a party. They would both talk to different people and gather different knowledge/information. And to answer your other question, I agree with rabbit. Person A is not connected to person B physically. So up until you provide life to person B, he will be exactly identical to person A, but person A can't control person B's limbs because person A's brain is not connected to it. Person B's brain is a copy of person A's brain, but it is now a separate entity. It's like backing up your hard drive to another hard drive. The data has been transfered, but afterwards, the connection is lost. The back up hard drive can be stuck into another identical computer, and it'll run. However, when it gets on the internet, it will have a different IP address, will it not? It will recieve attacks from different people than the original computer, and the time that it get information would not be the same a your original computer.
