My guess would be that an electronic magneto (i.e. the self powered type of electronic ignition) will have a capacitor and some smoothing circuitry and may need a few spins to charge up enough to make a spark?
Angular speed variation within a single turn at very low rpm is typically the issue, when there is an issue.

During the start sequence of the engine, the EIS sets the ignition timing to 0 TDC and does not begin to fire until approximately 50 RPM. This allows the engine to overcome compression strokes
