# Confusion about definition of ergodicity in Markov Chains

On Wikipedia I found the following section on ergodicity

Ergodicity

A state i is said to be ergodic if it is aperiodic and positive recurrent (*). In other words, a state i is ergodic if it is recurrent, has a period of 1, and has finite mean recurrence time. If all states in an irreducible Markov chain are ergodic, then the chain is said to be ergodic.[dubious – discuss]

It can be shown that a finite state irreducible Markov chain is ergodic if it has an aperiodic state. More generally, a Markov chain is ergodic if there is a number N such that any state can be reached from any other state in any number of steps less or equal to a number N (**). In case of a fully connected transition matrix, where all transitions have a non-zero probability, this condition is fulfilled with N = 1.

A Markov chain with more than one state and just one out-going transition per state is either not irreducible or not aperiodic, hence cannot be ergodic.

I added the asterisks myself. What's confusing to me is that (**) seems much less strict than (*) because it doesn't mention periodicity. For example the transition matrix $$P=\pmatrix{0&1&0\\0&0&1\\1&0&0}$$ seems to fullfil (**) because every state can reach any other state in 3 steps. Is (**) correct? Am I reading this wrong?
