American Express – signatures

I noticed that using American Express credit cards (Gold or Platinum) requires the customer to sign a copy of the receipt with a dotted line. What is the purpose of signing this receipt and if I accidentally signed the wrong copy (and the cashier mistakenly took that wrong copy from me), will there be any problems?

Also what if I signed in a hurry and my signature does not match the one on the back of my credit card? Usually the cashier is too busy to check so he / she just accepts it anyway. But if they don’t match can they reject the transaction?
