Unless /ison has a way of specifying to look at 1 $server, it looks to me as if the other replies are checking to see if the nick is on the $network, not on the $server. To check if they're on a particular server, you could do a /whois on them and check the reply to raw 312. Alternately, you can build a list of nicks using either:

/who +cs #channel_name servername.net

or

/who +s servername.net

and checking the return on raw 352.

edit: oops, nevermind, i finally see the $server name in the /ison raw reply.
