eli5: How come the computer pointer on the screen hides on the right side of the screen but doesn’t on the left?

When watching a video we always subconsciously swipe the mouse to the right so the pointer can hide on the right side but it will always rest against the left side completely visible why is that?

The position of a pointer is one individual point.

The pointer is always on screen. It corresponds to an individual pixel on the screen.

The image which represents the pointer is of course larger than one pixel, so that you can see it more easily and that it can have different shapes depending on the circumstance. A certain pixel in that image is set to be its origin and it’s always in the exact point of the screen that you are pointing. Every other pixel in the image is positioned relative to it.

In the most common shape of the pointer, the pixel at the top left is the origin.
