dei neutral saftey switch vs input

The python991 CM has a 2-pin header for a supplied SPST Neutral Saftey Switch and in addition I note that H2/18 pin is called Neutral Saftey Input. Are these basically the same input pins? In other words if the SPST switch is plugged into the 2-pin connector and the switch is on, does that in effect gnd the H2/18 pin or do I still need to gnd H2/18? Doing an automatic trans car here.

Thanks for confirming... seems like they could have come up with a better name for the SPST Neutral Saftey Switch so as not to confuse it with the manual transmission neutral switch input. They should have called the SPST switch a "Remote Start Disable Switch".
