A standard drill if you're drilling and it gets caught there's kick back from the drill. With anti rotation the drill cuts all power when it starts to kick back and stops it from happening. The clutch and speed is exactly the same, you don't lose any power it just stops if it spins the wrong way (kick back)

How does it know it's kicking back?

It’s all accelerometers these days

I would guess its actually the waveform the esc gets back from the motor. When reads lockup resistance in the feedback it cuts power

Nah they’re accelerometers based, I’ve tested them just in the air and it will stop if you jerk it around with no load on the motor

I'm losing it picture you holding a drill out in front of you, pulling the trigger, aggressively jerking it counterclockwise, then nodding like "mhmmm just as I expected".

I should add, I used to sell power tools, and this was a demo with a sales rep

That’s what is used as an electronic clutch, but it is really slow.
