Step-length does not make a difference in the default model because lane-changes are instantaneous regardless of the step-length. This means you will never see the vehicle on two neighboring detectors in the same time step. To get continuous lane changes you can enable another model: http://sumo.dlr.de/wiki/Simulation/SublaneModel Do you need the double detection directly for your project or are they a means to accomplish something else? In that case there may be other ways to accomplish your objective.
