Seems you haven't read the document properly. On the first line itself, it is mentioned "final maximum permissible speed of WAP-4 class of locomotive on tracks maintained to OTHER THAN C&M-I Vol-I standards". All 130 kmph tracks are considered under C&M-I Vol-I standards. (only NDLS-HWH via Gaya, NDLS-BPL, NDLS-LDH and NDLS-MMCT via kota as of now).
