Trying to xrealm hop with two accounts need help

[dsig111]

Ok so I have two accounts and I am trying to hop my main to different servers to farm same rare as much as possible. I know I saw elsewhere people doing this, however when I try to do it, the random toon I make on each server is the one to phase to a new server not my main account. It doesn't matter if I invite from main account or from the other account its always phasing the wrong account. Anyone know how to get it to phase the right account?

Incase I didn't make sence, say my main account is on illidan.
I make a lvl 1 on another account on a low pop server.
I invite my main account from the lvl 1 account.
The lvl 1 account phases to illidan.

I try the otherway around and invite the lvl 1 from main account.
The lvl 1 phases to illidan.

I can't get the toon on illidan to phase to the lvl 1's server.
