Strange observation of flight on map

Tonight I observed something I hadnt ever noticed previously on the map. Qantas flight QF/QFA551 had completed it's flight from BNE (Brisbane) to SYD (Sydney) as normal. It then flew flight QF/QFA497 from SYD (Sydney) to MEL (Melbourne) but the pilots didnt change the callsign. Hence if you follow the pics in sequence you'll notice the white bar in the blue route section on the info panel move from right to left instead of left to right (backwards) as well as the associated changes in the flight times;

The bar 'regresses' rather than progresses. I verified the callsign/flight number through Liveatc as it landed at MEL. The no callsign flight heading north out of SYD actually was a flight with no callsign but the no callsign at SYD is that of the ground vehicles. Thought I'd post this out of interest.

Gregg
