I was reading Deathly Hallows and got to the part where Harry remembers he didn't catch the Golden Snitch in his hand, but rather almost swallowed it. He had to touch the Snitch with his mouth before the Snitch would reveal I open at the close. I began wondering how the Snitch would react to the touch of its original owner's identical twin -- would the Golden Snitch react to the touch of an identical twin, and treat it as if it were the original flesh memory?
Please no Wiki/Wikia references; I'm looking for an answer based in HP canon. The books, Pottermore, and J.K. Rowling are all fair game. Subjective answers based in the spirit of canon are totally fine.
I am referring to the identical twin of the person who first caught the Snitch, not a random person who happens to be an identical twin. Just so it's clear.
