Did Junior5 consider 23...Rh8 instead of Rc5?

Junior4.6 rejected Rh8 only at depth 17 because of f5
I reject Rh8 because black loses a tempo after Qg7 Rf8 Qxh7

Junior4.6 rejected g5  and prefered 0-0-0 after a long time (less than 1 hour)
I think Junior5 will reject g5 if you give it enough time.
