Credit cards are not instant. They take several days before they post. And you can spend more USD in your bank account than is actually there up to a certain extent, causing "overdraft" (if you allow it). The hour that you wait for BTC is to make sure it can't be taken back. A credit card transaction can even be taken back after it has completely cleared called a "chargeback".

BTC is actually instant. You don't even need internet access! But to make sure it can't be taken back, we wait an hour.
