understeering is simply operating out of the tire's slip angle. you still have traction, just not enough of it.
keep in mind, mdm may also withhold power while this is happening. so if you're turning the car and it detects understeer, it may do both. it might even use both of the front brakes depending on how much driver input there is. as you know, it doesn't take a whole lot to correct understeer.
think of how much influence the front brakes have in turning, like trail braking... mdm is almost like the car is implementing some trail braking to get some more turn-in.

Correct. Grip is not completely lost but you’re turning the wheel more and more yet the front is not heading in the intended direction. It’s definitely not like trail braking. The point is to provide a correction that puts the front back on its intended path, not take the rear of its current correct path.
