You are right I wrote it in a hurry before going out with my friends.

But it is important because a debate about this part of the film was raging for years about weather Luke’s Hand and Lightsaber fell in to the clouds below. It was just a part of the weather vane

Nobody really totally understood why we saw that because the conclusion of the weather vane snapping and Luke falling was never shown. So people were trying to understand what it was they were seeing and were giving it another meaning. Which nobody can blame them for that (myself included at one point).

Because the meaning of the scene is obsolete because they changed it.

And Yoda training Luke to do Handstands and Lift up Objects is also Obsolete In a way… Not entirely but I think the training was to do with dealing with this predicament.
