I can't do timestamps for you because I don't have regional access but I think we're referring to the same thing (the twizzle exit of the OFst). In realtime, there seemed to be some debate about whether it was actually an OFSt in realtime since Gabi stumbled coming out of the twizzle and went on two-feet. I suspect that's where the original Pst label came from.
Oh yeah, it's at the end. Her twizzle is messy, she trips and saves it by stepping on her left foot when exiting. But Gui steps on his left foot at the same moment, it was the end of the twizzle and the end of the step sequence.
