Same here

Does the esp brake the wheel with least traction to force torque back to the opposite side of the diff?

Yes, ESP brakes the wheel which start spinning. Pre ESP like mine and Dezzy's does the same with EDL but only at slow speeds and does not reduce engine output. Brake force is limited so if you have one wheel without grip at all (in the air) you are still not going anywhere.
