It only made sense to me if you expected an imminent strike on something nearby. Any other scenario I would think you would be better off getting off the X, or finding some bit of terrain that would make you not the highest thing around.
It also seems to be that people already understand getting off the X. Locally I'm aware of one rescue when someone got off the X and got cliffed out (no surprise given the terrain) and I'm aware of one fatality where the details were never reported but the location of his body only makes sense if he got off the X and got cliffed out--but on the other side where there's no cell service and the missing person's reports made no mention of satellite stuff. I'm not aware of any lighting deaths in the area, though. (Of course the real answer is don't go up there in lightning weather! The day he disappeared I had been considering a hike but considered the weather a no-go.)
