Does Arcane help with the accumulation of Madness, Frostbite, Bleed, Rot, and Poison?

If the weapon does not have "Arcane scaling" (for example, "Madding Hand", will increasing the Arcane stat enhance the chances of proc'ing the status?

[Recjawjind]

Arcane scales certain status effects IF AND ONLY IF they are applied by a weapon that has arcane scaling (a little letter next to it on the item card, the better the scaling, the more the buildup is scaled of course)
However, only bleed, poison, sleep, and madness are scaled by arcane. Rot, frost and deathblight are not.

Why the need to say iff?

Thanks for the answer!
