Maybe even pay to (address derived from) contract hash has a hole: it assumes the merchant cashes the funds (or cashes then reimburses via the refund address). There is another rational (though abusive) move for the merchant: let the buyers funds sit in limbo. Then the buyer has the onus to go into disupte, maybe the seller is anonymous, in another country, or the cost of dispute resolution more than the value lost, and anyway its not very smart-contract like.
It might be better if the buyer has time-stamped evidence of having sent the funds to the merchant, and evidence of non-collection of funds by the merchant (by omission from the block chain).
