On a purely logical basis I agree with you, but this is comics, where people (specifically, Batman, who is intrinsically a point of comparison with Huntress) are allowed to be Just That Good. That is to say, if that were a mistake, despite it being completely incomprehensibly impossible to predict or anticipate, Batman nevertheless would never have made it. And if it's possible to avoid, it's possible to do on purpose (at least, by his thematic foil, it could be).
