The RTW booking tool appears to accept it, passes the validation checks ... but I've never successfully ticketed with this kind of itinerary with a generic error message at the final payment step. It's taken me a while to work out what is going on but the common element is this kind of routing, when I removed it the ticketing went through fine.
