We discuss branch points in the complex angular momentum plane formed by two Regge poles on trajectories with square-root branch points at t = 0. We find several new cuts which collide with the expected Mandelstarm cuts at t = 0. In the bootstrap of the Pomeranchon pole, the collection of cuts has the same effect as in the case of linear trajectories: The Pomeranchon can have alpha (0) = 1 only if certain couplings vanish at t = 0.
