When the couple are lying on the ground kissing in the opening, they both turn their heads to look (her to her right and him to his left) when they hear the lawnmower. But when the scene cuts to the POV of the mower heading towards them, they're looking in the opposite direction.
At around 1:31 Deke falls off the van roof onto the ramp. His legs are facing to the left. The next shot is a point of view from Deke, and his legs are facing the lawnmower. Several following cuts show various position of his legs.
