It's a very condensed verion of the reams of stuff that some posters have

not allowed during steady-state.

Stands to reason. Intentionally absent from the steady state are noise,
modulation, transients, and any other perturbation. It would be kinda
like opening the lid of an adiabatic chamber in order to see if the
internal temperature stays constant.
