// In other words,
console.log((o.a === {a}.a)); // true

I think that it should be without the dot between {a}a
console.log((o.a === {a}a)); // true

that's syntax error.
property access needs either dot (.) or bracket ([])

Yes you are that property access for objects requires either dot (.) or bracket ([]), but in the example we are talking about a string. Here is the result both in Mozilla Firefox and Google Chrome.

var a = 'foo';
undefined

{a}a;
"foo"

{a}.a;
SyntaxError: expected expression, got '.' [Learn More]



Please take a look in the example and correct the content in the documentation. Here is the full example(text) from the documentation:

(
    With ECMAScript 2015, there is a shorter notation available to achieve the same:

    var a = 'foo', 
        b = 42, 
        c = {};
    
    // Shorthand property names (ES2015)
    var o = {a, b, c};

    // In other words,
    console.log((o.a === {a}.a)); // true
);
