Tell me you have tested, before came here and say this...
It work perfectly fine, try it.
If you use //scid -at1 disconnect, it disconnect you from the first server connected, then waiting for the input request, then disconnect from the second server connect etc...
Also :
server -n irc.server.net | nick <nickname> | server irc.server.net
Additionally the /server command will allow you to specify the main and alternate nicks using the -i switch
-m and -i could/should be used
