Proxying with/without listen in server block

[tcbarrett]

Does having a listen directive in a server block over ride blocks without?

I have a slightly complex set up, proxying traffic depending on url to
various other machines on the network.

Something a bit like this: http://pastebin.com/MSAFJKLV

The middle block hogs all the traffic, and all requests are sent to
mysssl.example.com.

What am I missing?
