In short: yes. crgmask is not directly connected to the TI algorithms, all
it effectively does is tell sander to read a prmtop *as if* some charges
were zero. Note that the opposite is true for single-step TI. There a
distinction between SC and non-SC interactions, which are softenend, and
SC-SC interaction, which are not changed, is made.
