One way to check it is to run the HL/7 Tester using the IB variant and the message with which you are testing. Turn the noise level on the Tester to 2 and observe where the address path changes for each OBX.
I think you will see it change at 1(0).1(0).1(0) not 1(0).1(0).1(0).OBX.
So I think this is a group iteration not a segment iteration (usually is group). If it is your Source: would be 1(0).1(0).1(%g1).OBX(0).00573
Anyway, run the HL/7 tester and make sure.
