You're close. IRC in this case is a way for controlling hacked system. It 
is more simple to control many such systems via IRC than to connect each 
one.
When you have a group of systems listening for commands you do not have to 
burden yourself with giving commands separatedly, no need for checking how 
many systems has been repaired etc. You just control one IRC channel.

Of course it is possible to do that another way, but why bother if you 
have ready tool in your grasp
