Perhaps an equally important factor as intent, is whether an advantage gained is earned, or unearned. When there may be legitimate doubt, or question, to intent, observing the results may provide additional detail that add to the ultimate judgment.
As suggested, a sweep in the opposite direction is far less a factor in suggesting there was deliberate intent to gain an UNEARNED advantage, whereas a quick pass to the late arriving substitute may support such a conclusion and provide opportunity for applying a remedy.
