I short jump all the time if the last piece gives me less points then what that last jump will leave the other person.

Plus at the end of the game, when on a certain number of moves let and the game is close - stopping short will add an extra move in the game which may end up leaving you the "good" pieces to jump.

What I hate is I'll make this GREAT multiply jump with lots of points and luckly notice it is anti-froglet and hurry and hit cancle.... but only a matter of time before I make this mistake. :-)
