That's amazing! I never tried that. I do the same thing, but with a knife.
I would never want to eat a Salmon skin. The skin, and the meat just under the skin, is where all the bad stuff is stored.
If I was going to grill a Salmon, I would do so with the skin down to keep it from falling apart, but I would leave the skin on the plate.
I get Salmon much smokier without the skin, so I remove it for smoking.
My 2 cents.
