The additional weight (mass) behind the cg has to be offset with weight (mass) added ahead of the cg.

Indeed, nobody disputes this.

But the Jumo added a lot of weight forward too, remember?
Not only behind.
So correctly placed there is no need for additional weight.
In particular as the majority of weight seems to be forward in the Jumo 004.

There certainly seem to be more bits n pieces in those 60% percent mounted forward on the wing.

As we see Jumo jet, still straight inner wings.

So we are likely back to this:

On 1 March 1940, instead of moving the wing backward on its mount, the outer wing was repositioned slightly aft; the trailing edge of the mid-section of the wing remained unswept. Based on data from the AVA Göttingen and wind tunnel results, the middle section's leading edge was later swept to the same angle as the outer panels
