Any dual point system I've worked on had the 2 sets of points set about 10º apart/overlap which increased dwell which then increased coil saturation time.
Now this was for older 6 and 8 cylinder engines with distributors and one coil. You know, the old stuff.

British motorbikes were famous for dual points, but, each set of points was for one cylinder. One set was set/adjusted correctly and the timing for its cylinder was then set. Then the other cylinder timing was set by the point opening regardless of its gap setting.
