One spike gets Ground and one signal.
The other gets two Signals (you only need two Spikes)
The spike with Ground is used in forward-only mode for the signal.
The other spike is used in forward-reverse mode, the forward phase is for one signal and the reverse phase is for the other signal.
You could alternatively run ground back to the PD board and skip the Spikes altogether. There's nothing saying the Spike requires the ground to return through it.
