That's the reason the Picard Maneuver ceased to be a viable tactic after "The Battle": because subsequent writers forgot about it.
Upon watching "The Battle" again, I think I had mistook the Picard Maneuver as an FTL trick against LS sensors. But the dialogue makes it sound more like a limitation on how the FTL sensors work on the Ferengi ships and E-D. A "maximum warp speed" hop seems to be required to trick the sensors. Of course that doesn't address the obvious points of either firing on both images or shoot the closest one
DATA: You performed what Starfleet textbooks now refer to as the Picard Maneuver.
PICARD: Well, I did what any good helmsman would have done. I dropped into high warp, stopped right off the enemy vessel's bow and fired with everything I had.
RIKER: And blowing into maximum warp speed, you appeared for an instant to be in two places at once.
PICARD: And our attacker fired on the wrong one.
