What supermajority ratio? 2:1? 3:1? I'll assume 2:1
N(A,B) 2:3 not a defeat
N(A,C) 4:3 A defeats C
N(B,A) 3:2 B defeats A
N(B,C) 0:5 not a defeat
N(C,A) 3:2 C defeats A
N(C,B) 5:0 C defeats B
Every option transitively defeats every other option, so every option
is in the initial schwartz set.
The weakest defeats are (B,A) and (C,A), dropping them, we have
N(A,B) 2:3 not a defeat
N(A,C) 4:3 A defeats C
N(B,A) 3:3 not a defeat
N(B,C) 0:5 not a defeat
N(C,A) 3:3 not a defeat
N(C,B) 5:0 C defeats B
A transitively defeats all other options, and is transitively defeated
by no other options, A wins. [Technically: there are no votes prefering
A to the default option, so the default option wins -- but that's a
trivial issue.]

I don't know why you think this.
