Pretty much this. Disappear makes you unspottable, but not untrackable. Especially if the hunter already had the window open and clicked on your name after you hit disappear. I'm pretty sure that the same thing happens with burg's HIPS, but, tbh, I don't think that you should be able to be seen in any way at all while the 10 seconds (of both HIPS and disappear) are active. That means visible, tracking, pets, npcs, anything whatsoever.
