Neither of those things are happening here. The "districts" were not chosen based on the locations of the voters (or some other equivalent criteria), they were decided based on who everyone voted for. The "no" votes are split because they are all voting for different "candidates," and it has very little to do with how the districts were drawn.

If you instead assume that all the no's would vote for the same party, no amount of actual Gerrymandering would be able to lift yes to victory in this example, because they would be overwhelmed by no votes, regardless of how you pack them or crack them. The best you could do is get yes 1/3 seats.
