Spec says a op= b is semantically equivalent to a = a op b.

Spec lies, or at least is at odds with DMD.

I assume you're talking about the fact that code like this fails:
----------
class Qwert {
    Qwert opAdd(Qwert yuiop) { return this; }
}

void main() {
    Qwert asfdg = new Qwert;
    asdfg += asdfg;
}
----------
I entirely agree that this code should work, on the bases both of common sense
and of this spec.
