If they were blowing and stomping they didn't wind you at all. They likely saw movement or something they didn't like (shape, skylined?). They won't stick around if they wind you, they bust out of there, much of the time before you get anywhere close. (watch guys hunting through a spotting scope, deer run circles around them) If they are blowing or stomping, and you are on the ground perfectly still, they will start to do a circle around you until they get behind you or get the wind and then they are gone.
