Just a thought experiment, but multiple gaps are probably similar  to a 
series string of neon tubes. No current will flow in the circuit until all  of the 
tubes reach that critical ionization point. However, I can also see where  the 
ionization might cascade from tube to tube, (or gap to gap) starting at the  
ones connected directly to the transformer because of the high electrostatic  
field present right before conduction. The middle tube or gap doesn't see any  
potential until breakdown occurs to the one(s) next to it. So, there might  
be a very fast cascading effect in multiple gaps, but no current flows until 
all  are ionized. 
 
Just a thought,

I also believe that unlike topload streamers which grow over time, the  arc 
in the gap occurs simultaneously to all segments.

At the top load,  there is current flowing, both through the ionized streamer 
channel, and through  RF displacement current (which does not require an 
ionized channel).  The  ionized portion of the path grows over time.

In the gap, prior to the  bang, there is zero current as there is not an 
ionized path, and there is no RF  to support a displacement current.  Then at bang 
time, the gap instantly  becomes conductive for the duration of the 
bang-interval.  It's an  all-or-nothing proposition in the gap.
