I have exactly the same setup (i3wm, i3status and netctl) and the same behavior.
If I plug in the cable i3status shows both connections. I manage it, that I deactivate the
wifi-card with the hardware switch after I plugged in the cable and everything
ist fine. 
I couldn't get netctl to deactivate the wifi automatically.
