what is a non-impulse coupled magneto? (also a question, not a quiz)

What's the logic of grounding the non impulse-coupled mag during starting?
(Not a "pop quiz" - I'd like to know).

In article ,

says...

Assuming just one magneto with an impulse coupling, the other magneto is
shorted and the starter is engaged (by electrical relay, generally...I'm
not
aware of any airplane starter that runs the current straight through the
mag
switch).

Note also that this is true only of systems that use an impulse coupling
for
starting.

Of course, you could have just posted that information, rather than
turning
into a pop-quiz.
