No, that's not what the ELSD does in QD2.
The best way to think of the ELSD is not as an LSD at all. Think of it as a variable locking differential. The computer can leave the diff fully open (as normal), fully lock it (zero slip differential mode, haha), or somewhere in-between.
Contrast that with, say, the Toyota 4Runner that has a rear locking differential as an option. The 4Runner's rear differential is either open or completely locked. In that scenario you have to choose between spinning your tire in the snow vs dropping to 4LO and then locking your rear diff, or hope that they implemented some sort of selective wheel braking to try to make it like an LSD if neither of those other options are ideal.
In QD2's ELSD we get the best of both worlds: the benefits of an LSD when it makes sense and the ability to fully lock in the extreme cases. No need to choose one or the other, and we don't have to drop into 4WD Low to get the left/right rear lock, either. Note that the ELSD is only on the rear. In the front, QD2 uses the selective wheel braking to try to mimic an LSD... and there is no ability to lock the front diff.
shows the QD2 ELSD getting locked by the computer automatically on demand on a WK. The WK version had ELSD in both the front and the rear, so it could lock both axles.
