The fact that there is a stop (and an equipment change) should not be of any importance, unless it violates the transcontinental rule (I don't think that applies but need to check the specific wording).
I don't know why the tool has a problem with the return.
In the past I've had problems with these routes - especially QF108 JFK-LAX-SYD - the online tool books it as an intercontinental leg, but when I looked to get a travel agent to do the same, they could not get around it being split into QF108 JFK-LAX and QF108 LAX-SYD, which thereby triggers the US transcon rule as I already had a transcon in my itinerary. In the end I just booked it via the booking tool to get around the agent.
I'm just hoping I don't run into the same thing, especially since I can't get the oneworld booking tool to pick up my other US domestic flights. It just won't show them.
