Does the counterexample mean that the exercise is false?

Thanks @Asaf. I had no idea the axiom of choice has its own tag. :D

comment Topological Dynamics: closure of forward orbit vs. $\omega$ limit set
Do you know of a way prove that $\overline{\mathcal{O}^{+}(x)}$ is $f$-invariant not assuming that the space is first countable(i.e. that we can characterize continuity in terms of limits)? By the way, thank you for the answers and help everyone, they're very much appreciated.
