>According to it, an equal number of floors both from the upper and from lower part should have been destroyed.
nope
process of induction focusing only on a single floor:

can a single floor support a huge pile of rubble moving down fast? no
can a single floor support a huge pile of rubble moving down slowly? no
can a single floor support a huge pile of rubble not moving at all? possible

let's assume a floor failed, what happens to the next floor?

did the rubble's momentum slow down a little bit? next floor is getting crushed too
did the rubble's momentum slow down significantly? next floor is getting crushed too, because slow speed is still enough, also it's heavier now, having acquired a new floor worth of mass, so speed requirements are even lower now

did the rubble completely grind to a halt? the distance to the next floor is enough to accelerate it to a speed where it can continue crushing

in conclusion, it's unstoppable
even in the extreme case that crushing a floor will completely stop the rubble, the distance to the next floor is enough to accelerate it to a crushing speed again
and that's the extreme case, the actual case is that it only slowed the rubble's momentum by a little bit

the towers were fucked even in the best case scenario
