  We show the expected order of RNA saturated secondary structures of size $n$
is $\log_4n(1+O(\frac{\log_2n}{n}))$, if we select the saturated secondary
structure uniformly at random. Furthermore, the order of saturated secondary
structures is sharply concentrated around its mean. As a consequence saturated
structures and structures in the traditional model behave the same with respect
to the expected order. Thus we may conclude that the traditional model has
already drawn the right picture and conclusions inferred from it with respect
to the order (the overall shape) of a structure remain valid even if enforcing
saturation (at least in expectation).
