I ASSUMED (THIS WAS A LEAP OF FAITH)

Surely only one pair (From the list in the blue above) would be the product of 864. [I obviously did not multiply any of the numbers in the blue column]

Hence (s2) MUST BE sufficient as only pair (From the list in the blue), should give a product of 864

You made an assumption = you got lucky, jabhatta2.
Edited to add: we are guaranteed that 864 has more then one pair of factors in the 20s and 30s just by the rules of DS (a DS question can never be solved without statements).
