Hi,

There is no requirement on the sequence during endorsing. For this AND(org1, org2, org3) endorsing policy, as far as the client receives back endorsement from org1, org2 and org3, all with same result, the client will perform the next step, i.e. send a transaction to orderer. We specify the --peerAddresses in the CLI chaincode invoke command to specify those peer addresses for each org.
