To be more exact alpha beta is a function that givees you a number (alpha if the evaluation of the position after search is worse than alpha,beta if the evaluation after search is bigger than beta and a score between alpha and beta in other cases. If the evaluation of Na3 after search is 0.00 you are not intereted in the exact value of e4 if it is not better than 0.00 and your calculation will give 0.00 even if e4 is losing material so you will have no way to know if e4 is losing or leads to an equal position.
