But usually what can be legally on the left side on an assignment, can
also written on the right, and with the same syntax, and the same
levels of indirection.

 Yes, but what can legally be on the right side of an assignment very
often cannot be written on the left.  I don't call that "symmetric".

The symmetry is about when you /do/ legally have the same thing either side of '='. That is in contrast to BLISS where the RHS needs an explicit deref symbol, but the LHS doesn't.
BLISS, AFAIK, can also have unbalanced left and right expressions like:
   A = .B + .C + .D
which I believe is the point you're making above. Yet that was described as 'symmetric'.
Here's a more realistic example, negating a variable A:
    A  = -  A;            // C, described as 'asymmetric'
    A  = - .A;            // BLISS, described 'symmetric'
