Multiple wifi connections to my Pi

Hi,

Is it normal to be able to log into an EmonPi over wifi on two different ip addresses?

In my case 192.168.1.154 and 192.168.1.155

Open a webpage on both addresses and it will open Emoncms on the pi,

the pi setup screen from Emoncms only shows 192.168.1.155.

the lcd shows wifi on 192.168.1.155 and Ethernet on 192.168.0.164.
