Ok, so then my follow-up question becomes, does the right hand
sides of these two assignment share the same AST node? If not,
why?
Because such a shared AST node could be potentially mutated in
different ways in different contexts during its passes?
The spec says nothing about AST nodes. You can ask what DMD does
(I don't know), but technically speaking, ASTs are an
implementation detail of a compiler. A compiler need not have
ASTs at all to follow the spec (unless the spec demands ASTs to
exist, which I think it does not do). A compiler can change its
AST nodes to a different yet equivalent representation without
issue (unless the spec demands ASTs to exist and be of a certain
form, which I think it does not do).
