Why use .init for associative arrays?

I am just wondering why we should use init for associative arrays of structs. See this code for example:
S[char] aa; // associative array of struct S
aa["this_is_good"] = S.init;
aa["this_is_good"].nb = 1; // all right
aa["this_is_an_error"].nb = 1; // runtime error, compiles fine...
I can't see a use case for _not_ using init before accessing a new key, so why do we have to explicitely use S.init?
Why does this code compile fine (it gives an access violation error at runtime), shouldn't it always give an error?
