It's simple, although they don't even need to use paranthesis. Try this for example:

function display($var) {
   return $var;
}

$variable = display('test');
$variable2 = (display('test'));

echo "$variable <br/>$variable2"; //Both return 'test'

Just as your example shows.

 

what is it used for

 

It is of no benefit in this case, however parenthesis can be used to group expressions together so they are executed in the correct order.
