Making sense of NOR get output
... 1 ... 0 ...


You're thinking of it incorrectly.

CMOS transistors can be either open or closed, which do not translate to 0 and 1. If there is a closed path to Vss then the output of the gate is 0. If there is a closed path to Vdd then the output of the gate is 1. If there is no closed path to either than the output of the gate is high-impedance.
