The way the inputs work does not allow hooking something up to two inputs at
the same time while still keeping independent use of the inputs. You would
need to add at least diodes. I assume you want a pure LEGO solution, but
LEGO doesn't have a diodes. The non-LEGO mux and expander designs do not
have any problem with multiple hits at the same time. They decode all
possible states.

Let's pretend you had a LOT of the motor/sensor connector wires: Sensor #1 is connected to input port #1 hit = 1 0 0 Sensor #2 is connected to input port #2 hit = 0 1 0 Sensor #3 is connected to (...)
