I am no sure what page you found. The puzzle is discussed at

/SimpleGames/Horse.html.

It must be clear from the Hint that the minimum number of moves required to solve the puzzle is 8.

You may also argue that no piece can get to its final position in 1 move. Therefore, each piece must make at least 2 moves.
