You mean there's a difference? I think itching happens so you will notice how good it feels when it stops.
I think it serves the purpose of agitating the area that's irritated and drawing blood flow there. It's been suggested that that's part of the effectiveness of acupuncture as well — drawing the attention of the body to an area that needs it.
