if this was a world record, would it count? they obviously reversed the track to gain the tailwind.
PS. how many people actually care what categories they put their new post under?
Of course it counts.
There is no 'direction' in a 100m. If they reversed the direction of an event that used bends, or ran the 200m with the straight first or without a bend then it wouldn't count.
Other than assisting with wind direction, how would the direction of a straight race have anything to do with the legality of performances.
There are no rules of orientation of a track (ie; facing north/ south etc) there are only rules regarding the shape and length of a track.

At the Heps at Yale this weekend, they ran the 200 trials Saturday from the finish line to the 200m mark (had a set of cameras there) and from what I heard did it Sunday, as well as reversing the direction of the straightaway races.
thats legal....it doesn't matter
