I feel it would have helped if the card said "non-warlord unit". (Then we wouldn't be in this mess.)
But since it doesn't specify i figure the card checks the folowing:
A) Is it a (space wolves) unit? Yes? go to B.
B) Is it at a planet with your warlord. Yes? Resolve effect.
And your warlord is always at the same planet as your warlord. Because it is imposible for your warlord at a planet to NOT be at a planet with your warlord. (It can't be in two diffrent places at once.)
I've also checked the defination of the word "with". It doesn't help.
