It looks to me as though deathjump spiders were 'supposed' to have the death from above on a somewhat limited basis - something like every other round, by saying that they MUST shift 6 squares to make the jump.
One of my reasons for suggesting this is DMG p42, where the 3d6+ damage they do would be a 'limited damage expression' for their level, and not something you would expect them to do every round.
Another reason is that as a skirmisher I would expect it to be moving in, attacking, moving out again, getting to a good position and then moving in to attack again.
A third reason is that (as evidenced above) used in other ways enable them to slaughter parties much more quickly than you'd expect them to be able to.
Cheers
