If anything, I'd say that Xykon would look at that pillar, chuckle for a few moments, and go "who wants to bet that it's absolutely right here?"
He only left so quickly because of two factors: He knew first-hand that Girard's Gate was destroyed (the explosion and rift being hard to miss), and MITD's interference. Without that definite proof that Girard's Gate was destroyed, he wouldn't leave the coordinates, if only because if one set of coordinates were false, so might the other, the ones that he'd be using for Kraagor's Gate. Already there, after all, might as well spend a while making sure... and blasting the whole place for good measure too.
