Agreed. For some reason it reminds me of something akin to:
_____________
#include <iostream>

struct foo
{
     int a;
};


int main()
{
     foo a = { 0 };
     foo b = { 1 };

     {
         foo const& r = (true) ? a : b;
         std::cout << &r << "->a = " << r.a << "\n";
     }

     {
         foo const& r = (false) ? a : b;
         std::cout << &r << "->a = " << r.a << "\n";
     }

     return 0;
}
