GestureRecognizerClearTrackedTouchesOnEndOrFail Property

Whether tracked touches are cleared when the gesture ends or fails, default is false. By setting to true, you allow the gesture to possibly execute again with a different touch even if the original touch it failed on is still on-going. This is a special case, so be sure to watch for problems if you set this to true, as leaving it false ensures the most correct behavior, especially with lots of gestures at once.
