The purpose of the position command rate-limiting (RLPC) is to help M2's integrator keep up. Yes it's an integrator so it's going to lag somewhat, but don't forget the contribution of M2's proportional action which has no lag.
The best way to settle the matter I guess is to run it on hardware or a simulation.
