Why? Because that's the most efficient way of doing it, I'd gather

Rather than some clever efficiency thing, I'd have thought it was simply because {} returns a scalar value. ('A') x 10 would give you 10 copies of the string 'A'. Similarly ( {} ) x 10 gives you 10 copies of a reference to a particular anonymous hash.
