Because his arm caused his body to go sideways and eventually his foot landed, posters are confusing that with "spinning around". Its not the same thing as when he rotates into a normal forehand.
I think that so many have this belief that you must transfer your weight forward and players always hit from back foot to their front foot. Which is so far from what really happens in match play.
Thats why i used rafa as an example, he hits off his back foot a lot, but so do the other players. There are times like you pointed on that a player must only hit with the arm. That is why they pull up and back, they need to make enough space to be able to swing, plus they can get some power from pulling up and backwards. Thats right despite popular belief you can get power from moving your weight up and back.
When players do this you will see their front leg come off the ground, then it will go around and land to the side or behind them. The only way this can happen is if their weight is coming back, there is no forward weight transfer. When they have time to set up they will transfer their weight forward, but many times they don't have the time or court position to enable it.
