Maybe 'clear' was the wrong term, but I was referring to chargebacks. Their only concern with Bitcoin is also fraud, since that's what double spends are too.

Also, I happen to be a previous Namecheap customer with a credit card attached to my account. If the Bitcoin payment had failed, they could have just charged my account/credit card to avoid their loss (possibly with some extra legal annoyances, but I don't think there is anything fundamentally wrong with that).
