Yes, but apparently the routing information associated with it is still in the 
routing tables. You said so yourself - that there were two default routes, one 
for wlan and one for eth0.

The TC/IP routing software is going to use what it finds in the routing table. 
If the destination doesn't match a specific network in the table, it will look 
for a default route.

If, for some reason, it decides to prefer the eth0 route, that's where it's 
going to send the packet. When it gets to the physical layer it will find out 
it can't actually send it, and the transmission will fail.

If the metric is the same for both default routes then it's very likely it just 
uses the first one, which may or may not correspond to how they're listed on 
the netstat output.

You should only ever have one default route.
