AF459 Sao Paulo - Paris : aborted landing 16 Aug 2016

I saw this plane from my window, and couldn’t understand why he was climbing from east to west. So I looked him up and found he had aborted his landing at 11h20. I watched him on screen do this big loop to come in again and finally land at 11h39
But did he really do a 180° turn from N to S and back at 10h53 with a nearly 50% drop in speed ?
