In fact Vds is between -50nV and +50nV. In the simulator the output seems to be linear, but is this in reality happening? What happens if Vds goes a few tens of nV below 0V ? Vgs=5V constant (on state)

For most MOSFETs with source shorted to substrate, it ends when the drain-substrate diode starts to conduct.
