That's a markov chain of the 1st order.

This is higher order Markov chain

I think Markov chains have transition probabilities, which this model is lacking. But it's the same idea, just with uniform transition probabilitis.

It seems like it has transition probabilities.

Depending on the type of the prior word, it randomly selects the next word from a list of compatible word types.

Am I misunderstanding?
