I have 2 questions to about the card Saw In Half | tcgmode

Question 1: what happens if I target a 1/1? Do I get a 1/0 and a 0/1 or 2 1/1s? Question 2: if I were to target a mobilise warrior token, would I sacrifice both the copies or would they both no longer be sacrificed as they’re no longer tokens made by mobilise?
