wait until the timeout).
Also: THE ABOVE SCRIPT IS NOT THE MOST EFFICIENT SCRIPT POSSIBLE FOR THIS USE
CASE!!! This is to illustrate a similar conceptual use as current 2-of-3
multisig. Realistically, you want to do <EscrowPreimageR> *OR*
<SenderPreimageR> since the recipient will always redeem if they can. So the
hash code block would be instead:

OP_SWAP

OP_HASH160 <SenderHash> OP_EQUAL
//Stack: <BobSig> <OP_1> <OP_0>
OP_BOOLOR
//Stack: <BobSig> <OP_1>
OP_VERIFY
The tradeoff is that if the escrow fucks up, then payment can be forced.
Whereas the original script doesn't have that problem if the receiver does not
misbehave.
