I can see where it might be possible that there is a control loop setup between the traction control elements monitoring the slippage of the front wheels

and the clutch controls monitoring the RPM's of the gears

to where the TCM (transmission control module) starts to activate the clutches, as the ESP (electronic stability program) starts to notice the wheels moving.

and between the 2 systems they are pulsating for a moment until the wheel speed of all 4 wheels is consistent. Curious - how does your car behave on wet ground?

I've gotten mine to spin one wheel on a hard start, but only one and IIRC it is only the left one. (shortest drive shaft)
