I don't think she rows back at all. If you're referring to the phrase 'There is no suggestion that Prince Harry...' was being racist/misogynist etc, that's not from SC. That's the FT editorialising to cover themselves legally. That's not to say that SC doesn't have evidence of bad behaviour from PH, and that she hasn't supplied it to the charity commission. It just means that the FT hasn't seen it.
At the moment, SC is winning the PR battle because she's going on the record which signals confidence in her complaints. PH's side on the other side is definitely briefing the media, but is doing so either off the record (Bryony piece) or on background (the various unattributed quotes).
That doesn't mean that SC's side is the right one; I suspect that there are two valid sides to this story. But it does mean that PH's team isn't willing to put him or someone from his side on the record - either because they fear it will make him look undignified (never stopped him before tbh) or because (more likely in my view) his legal team don't know exactly what documentary evidence SC's side might have and is worried he'll get put on the spot with a curveball question.
It seems to me that PH's / the old Trustees' side is using PRs and 'friends' (like the Tory peer) to proactively brief the media against SC, whilst Harry's legal team is handling right of reply type queries. The fact that lawyers are handling these is highly significant.
If I were a betting woman I would say that in the coming weeks and months this is going to turn into a wider scandal around allegations that the Sussexes misuse PH's charities for their own PR efforts (ie they use them to PR the Sussexes rather than the charity). Possibly also allegations of misuse of funds.
All of that to say that reading between the lines of what's out there, we can see both sides marshalling their forces and so I think this has all the hallmarks of an opening skirmish in a much larger, noisier and more tawdry set of alleged scandals.
