I don't see a reason. Alt has been used ever since the first version that
supported horizontal scrolling. There are no hints in the old commit history
why it was chosen.

Alt+WheelUp = left
Alt+WheelDown = right
Up = towards lower coordinate numbers
Down = towards higher coordinate numbers
Wheeling down with and without the modifier will take you from Top-Left to
Bottom-Right.
