It's a similar issue, I think, to shadowing in C/C++. We can have

int foo;
code;
if (condition) {
    double foo;
    use(foo);
}

and the behavior is well-defined but not recommended, so we have -Wshadow. The {...} in an f-string is a similar kind of inner scope. Re-use of the same quote character can be confusing and perhaps might produce a warning, but it's not difficult to parse, and forbidding it can be more work than letting it pass.
