That's correct.
And you can always run the Kv test with a lower voltage too... it will still work correctly.
So, if the application is for 4S, you can run the Kv test with 2S if you are worried about overspeeding the rotor.
A lot of cheapy motors out there are skimping on rotor materials -- so the concern is not unjustified.
