Tony, in short No.
When you say "impact" I'd like to point out that a jet strikes harder in the center of it's spray pattern than it's edges. So we want a 30% overlap to help to even out this impact discreptancy.
Now to be fair, your illustration is very close, there would be little difference between the two in practical application, you would have to offset the angle more drastically to be noticeable.
Larry, we have different info:
"FloodJet spray nozzles feature a wide angle flat spray pattern with medium impact. They produce uniform spray distributions of medium-sized drops.
A round orifice and large, unobstructed flow passages minimize clogging problems. FloodJet nozzles are also suitable for use with air and steam. All FloodJet nozzles offer a precision-machined deflector surface which provides dependable, accurate control of deflection and spray angle."
