Answer 1

It’s because the tip of the mouse arrow on screen is where the mouse pointer is.

The rest of the arrow is just there so we can see it better.

So you can move the tip all the way to the edges of your screen in order to click stuff at or near those edges. On the left and top sides the rest of the arrow will be inside your screen and visible, on the right and bottom sides, the rest of the arrow is off screen and cannot be seen.
