First example of h2syn in MathWorks

Hi:

Please see the Mathworks first example of h2syn:

Example 1: Stabilize 4-by-5 unstable plant with three states, NMEAS=2, NCON=2.

rng(0,'twister'); 
P = rss(3,4,5)';
[K,CL,GAM] = h2syn(P,2,1);

According to the definition: [K,CL,GAM,INFO]=H2SYN(P,NMEAS,NCON)

So, I think the 3rd line should be (NMEAS=2, NCON=2)

[K,CL,GAM] = h2syn(P,2,2);

Why is it not true?

Thanks,
