This is incorrect; comparison of atomic constraints is based on them

Two equal atomic constraint expressions do not necessarily share the same tree,
so we can't assume that two ATOMIC_CONST_EXPRs are equal if and only if they
point to the same tree. The main consequence of this invalid assumption is that
the constraint subsumption checker may reject a valid partial
