Yes. the analyzer traces starting from the given DeclRefExpr, e.g.: int a; // <- varDecl const int& b = a; // <- first DeclRefExpr int& c = a; // <- second DeclRefExpr const int& b2 = b; int& c2 = c; c2 = 10; If we start from the first DeclRefExpr, we'll only trace to `b` and then to `b2`. We need to start from varDecl (or loop over all DeclRefExpr) to be able to trace to the second DeclRefExpr from where we can get to `c` -> `c2` -> `c2 = 10`.
