You guys notice i am staying out of this discussion. Too confusing for me.
However think about this for a minute.
Without a condensor the current ( 3-4 amps) continues to flow when the contacts begin to open (001-etc) (jumping the small point gap) causing a arc.
This would in some cases make the car NOT run or run very poorly based on lack of control of the circuit (that needs to see a clean on/off ).
Using the path of least resistance the condensor provides a temp storage of the voltage allowing the points to open without arcing.
By the time the condensor "loads" (capacity in mfds) the contacts close and dumps this voltage backinto the primary circuit..allowing the circuit current to again flow and does it again.....and again.....
