Does anybody know the answer to this?

When you're at the doctor's office, and they're doing the hernia test where they palm your nuts, and he tells you to "turn your head and cough," is there anything medical to the "turn your head" part?

I mean, I understand the cough and the nuts part.

But what I'm asking is, does the doctor not want you coughing in his face, or is there some kind of medical occurrence that happens between your lungs, diaphragm and nuts when you turn your head?
