Cosmoc, I'm in the South East of England, but picked up the A380 over Australia using the network so it was probably picked up by your RB and shared on the RB network. I set up an alert for the A380, so I was alerted as soon as it popped up on the network, you can see this is from the network because the * is displayed after the flight number SIA221*. But it does illustrate how useful the network feature is, especially if you are interested in a particular aircraft.
