The way I read it is that Tab threw the sword, realized the pillar was still up, so instead of turning around, he just kicked off the base of the still standing tower, which would allow everything to have happened with changing any events.

Not sure how it would be read that way, as he threw the sword after he fell.

His landed on against the ice tower then struck it. Since he rebuilt the tower back instantly and no one fell, he simply kicked off of it.

[i]He hit the other tower with both feet planted before him[/i], and then aiming for a fissure where the strands of cryokinesis energy bound the tower into its current state, he cut right through a segment of ice, and through that very strand of energy. The effect was instantaneous, with most of the tower instantly dissipating into whiffs of water vapor. In essence Khazna had dispelled the ice tower, which inevitably caused Khold to free fall, along with a few chunks of ice spared from the dispelling effect. Of course so was Khazna, but the drop was only a couple feet off the ground, and he was expecting the drop. 

He fell into a crouch which turned into a roll and sprung to his feet in one graceful motion, the whole maneuver taking no more than 2 and a half seconds, most of which spent in free fall. He had hit the ground mere second before Khold, due to his slight head start, though the man was still 35 feet away. Even with his abnormal speed he would never catch him before Khold hit the ground and readied some sort of hasty defense from the unexpected hostile action. He probably never imagined Khazna was capable of destroying his tower so quickly. An easy feat with all that time he had finding the focal point of energy.

So without a moment’s hesitation he threw his blade like a spear aiming for where Khold would fall a moment behind. Should it hit, the blade would easily pierce right through his lower abdomen. Normally he would resort to a mock blade, but there was simply no time. Whether or not it struck, Khazna was already sprinting forward, mercy flashing free of its scabbard as he ran, and if it missed it would pierce another pillar of stone behind it. [/quote]
