Does Marked for Death apply for other Hunters' Hunter's Marks?

Hi again, another hunter question here. Let's say another hunter casts Hunter's Mark on your target. Is the talent(Marked for Death) still applied on the target even if you did not cast your own Hunter's Mark?

Thanks.

yes, you get the bonus as long as the target has hunter's mark aura on him.
