What the exact intention and the expected result ? 

user8717: Check the third output script:
OP_1 032487c2a32f7c8d57d2a93906a6457afd00697925b0e6e145d89af6d3bca33016

Essentially it's saying that in order for the transaction to be valid, the input script (scriptSig) must provide signatures for one (OP_1) of the public keys listed above.
So both the owners of the private key associated with either 032487c2a32f7c8d57d2a93906a6457afd00697925b0e6e145d89af6d3bca33016 or 02308673d16987eaa010e540901cc6fe3695e758c19f46ce604e174dac315e685a can validate that output.
This allows for scenarios where you need one of multiple entities (escrows) to validate a transaction before sending it off to someone.
