Take the following as truth: The catcher also gives signals to the infielders, letting them know what to do in case of a double steal, or what to do if a runner at first tries to steal when there's also a runner at third.
Then the following statement: "If a runner is stealing a base, the catcher will signal the infielders by wiggling his rump." is true, false, or inconclusive?
Answer: Inconclusive
