Good catch. The correct behavior, based on how the Java sim works, would be that the first backwards step moves the cursor to the end of the recorded data, which is at the end of the chart. That's clearly not happening here. I'll fix it.
Assigning to @ariel-phet so that he or someone on the QA team can verify that this is fixed on v1.0.0-rc.2 (http://www.colorado.edu/physics/phet/dev/html/neuron/1.0.0-rc.2/neuron_en.html).
