Actually, I think your shortened chain can be written without the commas. SpAce advocates the use of the commas to indicate a required ordering of candidates and cells. In this case, the cells in which the candidates have to be is unique. For example, (3,9,7)r4c961 can only have the 3 in c6, the 9 in c9, and the 7 in c1. If you want to use the commas in SpAce's fashion, then it should be (3,9,7)r4c691, but it isn't necessary here.
