CCE.cash is perhaps a unique exchange that has a specific feature where it is possible to receive several different currencies within one swap order. Maybe it's a way to send a specific amount in one of the currencies
You are right, this is one of the best features that if we send one type of coin like usdt, we can get different alts in different addresses, this is best for everyone participating in different defi and other liquidity projects and mostly it will be a project coming from heaven for airdrop hunters because I remember the difficulties in getting ETH testnet now they made sure the wallet must have some eth first, which was not so easy for airdrop hunters but they can easily use this service to get multiple type of assets easily in one go.
