Can't this arrow function be shortened further?

In the section on Practice Arrow Functions in JavaScript, under the video Debug Arrow Function Expressions there incorrect code of:

const printDate = date = function() {
 console.log(date);
}

is answered with:

const printDate = date => {
 console.log(date);
}

but shouldn't it have been shortened/answered as:

const printDate = date => console.log(date)

Curious to know if there is a reason to it not being made into one line?

Hey! So I did some research and I found from MDN and some other resources.

You can take the brackets out if it is an expression (3 + x) but if it is a statement you need the brackets. So it is possible they wrote it that way because of that reason. If someone has a better explanation I am curious myself.
