What I think is that anisotropic coupling may be faster in equilibrium. Suppose
the protein is quite different in x and y dimensions, after insertion, I think
it is faster to get equilibrium the box length separately. I agree with you that
semi-isotropic coupling in the first step can also do the job, but I expect it
may take longer time to reach equilibrium.
What I generally see is basically the opposite. Using anisotropic pressure
coupling leads to a steady change in box dimensions, but this is not the case
with semiisotropic coupling. It depends, I suppose, on how one produces the
membrane protein system - adequate deletion of lipids can accommodate for a
protein of any shape without affecting box vectors.
