I played a PvP against Dyvimtvar, won (at last!) and looked to make sure I got my points. There were two messages saying I'd won, and I got 400 points total added!
Since I lost by D/C earlier (to Aubrey), I humbly ask to keep my extra 200

If you need a screenshot I have one...
I've occasionally seen two win announcements at the same time (not mine) but the one time I asked he said there was a quick disconnection for his second win.
