The reason why most see the Cheetah as a possible reverse block is generally because with it being shorter in length, it cuts down on the perceived hold, one thinks its a reverse block. The shorter the conditio/pattern the more the optimum attack angle is farther towards the gutter or away from the pocket, as well as having the ball slow down properly.
Many perceived reactions are due to either using the wrong ball and/or in the wrong part of the lane at the wrong time.
