Reversibility of chordal SLE with force points

Let $\beta(t)$, $0\le t<\infty$, be a chordal SLE$(\kappa;\rho_-,\rho_+)$ trace started from $(0;0^-,0^+)$, where

$$\kappa\in(0,4),\qquad \rho_-,\rho_+\ge \kappa/2-2.$$

Let $W(z)=-1/z$.

Reversibility of chordal SLE with force points. After a time-change, the reversal of $(W(\beta(t)))$ has the same distribution as a chordal SLE$(\kappa;\rho_-,\rho_+)$ trace started from $(0;0^+,0^-)$.

This asserts that inversion in the unit semicircle, followed by time reversal, preserves the law of the force-point SLE trace while interchanging the two force points. The supplied text does not state whether the result is proved or remains open.
