It means that even if one of them is benefic in such horoscope, Kaal Sarp Yog may not form in such horoscope.

Based on placements of Rahu and Ketu in various houses of horoscope, 12 types of Kaal Sarp Yog exist; from Anant Kaal Sarp Yog to Sheshnaag Kaal Sarp Yog. The book features a chapter on Kaal Sarp Yog and 12 chapters on different types of Kaal Sarp Yog. Important factors which may affect the results given by Kaal Sarp Yog are discussed in details.
