Why are Actions called with a default constructor parameter of 0?

In /system/expressionengine/libraries/Actions.php, around line 185, Actions are called using a default parameter of 0:
// Instantiate the class/method
$ACT = new $class(0);Curiously… Why? Is it specifically to keep classes requiring a constructor parameter from loading in/as Actions?

Here the $class is a variable for the class name and class object is being instantiated dynamically. I think, this is used to avoid the error of mismatch parameters passed into contructor of that class.
