Well, the thing is, that's (one of) the rules for a UA code. But if it's an SK code, I wouldn't expect it to be used.
But I may have missed the AC A fare part, because I wasn't expecting to see rules for AC fares there

So, yes, when I said earlier that if it were a UA code, it would have been available as R, I was doubtlessly looking at the wrong line.
