What is this right hand called? (VIDEO)

[automaton89]

is it a sweeping right hand, haymaker, or an overhand right? What's the difference between the two?

in other words: shoulder level looping and descention.

Lennox Lewis liked to throw it. Seen Wilder do it too.

Haymaker and Overhand = same thing?
