The engine Houdini has the same option under the name "FiftyMoveDistance"
The effect of this option can be seen in the following example position:
5BK1/5p1N/5Pp1/6P1/6k1/8/b7/7q b - - 0 1
The best move is Qxh7, and with 50-move-rule Houdini doesn't find this move in tournament time, but with a 12-move-rule it finds the move in some seconds.
But the same experiment doesn't work in the engine DON
