When a player is riding any animal, whether it be a horse, pig etc., the game assumes that the player is in the air because they are not touching the ground despite the animal being ridden being on the ground.
The main concern is navigation when riding taller animals like horses mules or donkeys because clearing out leaves when riding through forests discourages players from using animals for transport.
