With HD wallets you can generate receiving addresses based on the master public key of a wallet, without needing any private key.

Is there a reason for not receiving funds straight into the cold wallet?

Edit: in the docs it seems that you indeed receive funds directly in the cold wallet

You are right. You can go from external entity to cold wallet directly. The important piece is how the funds leave the cold wallet.
