I don't think so. You only need 1 flight to locate him pretty accurately. If you do the thing you said, you'd need 2 flights along different axis to get a pretty good idea, with a larger amounts, you'd just improve accuracy a bit. Regardless, I think it doesn't matter. So what if they know where he lives, it's not like this sort of information is hard to come by anyway, and the risk profile of this is... not interesting, IMO.
