Porcupine cough?

I am only a student of TCM and browsing the net for acupuncture formulas I came upon this one:
Cough:

This is a formula given for cough!? If I do this obviously the patient would literally look like a porcupine. Unfortunately no explanation to this 'formula' is given so I'm not sure what they mean by all these points but I highly doubt that this would be one formula for cough. I wonder if they meant that you pick one of these points on each of these meridian depending on the type of cough?

Any thoughts?
