Both of those outcomes are because the hypothetical voters made stupid decisions, not because the system is flawed. If they choose to not take advantage of writing out all their preferences it's their own fault when they don't get what they want. I don't see how FPTP would be better in either example, you'd just get the same or worse outcome.
