I'm not sure there really is a "reason", per se. The language could just as well have been designed not to require parentheses around the return types (at least I see no parsing ambiguity with that, though there might be) or designed to require parentheses in the return statement. It probably just felt more intuitive and readable to the designers at the time.
FWIW I find it more interesting that `func() T` requires no parentheses, but `func() (S, T)` does.
