I just reread DHs and I came to a different
conclusion. 

Draco had been the one who disarmed DD with
Expelliarmus, but, since the Elder Wand had flown out
of the window, Draco had never possessed it. However,
the Elder Wind accepted Draco's ownership due to the
fact that he had disarmed its previous owner. But
Draco never had the Elder Wand in his hands.

While Harry and company were making their escape from
the Malfoy mansion of evil, Harry physically took
Draco's wand from him. This changed the ownership of
the Elder Wand from Draco to Harry. When LV attacked a
fighting Harry in the duel in Hogwarts, the Elder Wand
would not fight against its master and turned the AK
against LV.
