may I ask why you decided to copy paste my code from earlier into a context to make it seem like your own? even after the topic has been effectively finished, and the code you pasted changed.

He said the fall damage was still being negates this is your code but it fixes that.

The fall damage was fixed, that's what we added the event for. we removed the fall damage statement from the on update method as it was not wanted, and is a messier way of doing it, as other mods may set fall damage after it, based on speed or whatever. using the event will guarantee that the fall damage is negated, without having problems with other mods.
