The standard client's wallet includes a key pool of 100 extra pre-generated addresses, which are the next ones to be "generated" when you ask an extra address.
Does the blockchain.info's backup wallet do such a thing, too?

No, it doesn't. At least not from what can be seen in the "Export Unencrypted" option and I doubt that it would be any different using the encrypted option.
