Yes, it will. What it will do is increase the speed difference between players. At 40-50, there would be quite a bit more difference in the speed on the field. You can go into practice mode and test that out if you want to--pick a vertical route, just let the guys run down the field, then go into replay mode and see when the two outside receivers (they start from the same place) cross the 50. Check who wins and by how much. Then go in and lower that threshold setting and run the same play again, then check the replay. It may take one more play for the setting change to register, but you should definitely see a difference.
