Well as others have explained, the Expelliarmus didn't
/crush/ the Avada Kadavra. But I think more is going
on that others have indicated so far.

It has been established in GoF that Spells can collide.
We see this happen when Harry and Draco duel in the
hall outside of potions. The spells collide and ricochet
off of each other and hit by-standers. Later in the
story Voldemort and Harry's spells collide head-on, and
induce the 'Brother Wand' effect. 

In the final scene, Harry can sense Voldemort's spell 
coming long before it is actually cast. That allows
him to time his counter curse so that it will also
collide with Voldemort's. 

Next, switching of wand allegiance is not cut-and-dried,
not governed by clear concise rules. Even Mr. Ollivander
admit that he, with all his experience, does not 
understand it completely. 

Harry tells Voldemort of the sequence of events that 
lead Harry to believe that he (Harry) is the true
master of the Wand. Maybe he is right, and /maybe/
he is just trying to shake Voldemort confidence. Maybe
the Elder Wand recognized Harry and maybe it recognized
Draco's wand. I'm sure this carries some weight, but 
I'm not sure it carries the full weight of what 
happened when they  exchanged curses. 

None the less, a sequence of several events occurred 
that caused Voldemort's own AK to rebound back on him.
Whether reflected by Harry being the Master or the 
tendency of curses to collide, both, or even more things,
it is clear that Voldemort's own curse killed him.

I think to some extent, JKR indended for it to NOT be
crystal clear exactly what saved Harry. Certainly,
several aspects are clear, but how they all add together
and how critical they each are remains a mystery. Harry
is simply 'The Boy Who Lived - Twice' ..no make that
three times.

Just a thought.
