Here's the whole thing:
"The one with the power to vanquish the Dark Lord approaches... born to those who have thrice defied him, born as the seventh month dies... and the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not... and either must die at the hand of the other for neither can live while the other survives... the one with the power to vanquish the Dark Lord will be born as the seventh month dies..."
I'd say it means that "one" person will have the power to kill Voldemort, not "two" the prophecy, as has already been stated, does not apply to Neville due to the fact that Harry was marked (chosen) as his equal (his scar).
So you can say the prophecy isn't true and that it won't happen that way but I don't see the point of having a prophecy to begin with if its not going to play out that way
