Or at least that's how we were advised that's how it went when I was on the Star desk at AN. I personally wouldn't ever allow a ticket with a routing like that to be issued as per the application paragraph rule, but if you can get it done, then go for it!
You can interpret this part differently though.
If you pass through your point of origin again before you really travel around the world (which is another requirement for a valid itinerary), you might be fine. Only once you are coming back after you completed your round the world travel you definitely cannot go through your point of origin again.
Tricky...
