Either you follow the rules or break the rules, there is no "rudimentary syntax". They are brute-forcing the syntactic phase of the communication and they cannot generalize for the rules if it's not directly part of their current experience (pain,punish,reward etc). But almost every mammalian can reference to the world, hence the morphemes are almost there, but not quite.
