Why? They would be separate transactions on Blockchain

• DennisP 9y ago
  Ethereum is different from Bitcoin in that it uses simple account balances, which are easier to deal with in smart contracts. To prevent replay attacks, each account has a nonce, which is included in the transaction. You can check the blockchain for the current nonce of an account, but if you sent from the same account simultaneously from two devices, both transactions would get the same nonce and one would fail.
