ELI5: Why is it when I move my cursor to the right of my screen, it disappears, but to the left it stops at the edge?

Similar question for up vs. down.

Edit: Has to be the fastest answered question ever.

The actual position of the cursor is at the end of the point. That position stays on the screen - on the left, that doesn't allow any of the rest of the cursor (which extends to the right) to fall off the screen, but on the right, the actual position of the cursor can be on-screen even when most of the image is not.
