Impedance of an Un-energized SPST

What is the impedance of SPST switch like ADG801 when it is un-energized (no supply to VDD)?

 

I downloaded the SPICE model and tried to measure the SPST impedance with VDD = 0V.

I provided a 1V supply to the "D" and connect "S" to the ground, and I measured a 161.5mohm of impedance.

Isn't a normally-open (NO) SPST will be in open or high impedance state when un-energized?
