If you go up from 4s to 6s, your motor will draw less current if the total motor rpm is the same, for example a 3000kv motor on 4s (= 44400rpm) is drawing more amps than a 2000kv motor on 6s (also 44400rpm).
Right, changing the gearing affects the mechanical resistance. But since a motor converts electrical energy into mechanical energy that mechanical resistance is a factor here.

We're talking about increasing the voltage on the same motor, and its effects.
