Life Orb boosts the amount of dmg you do, but drains off a little HP every time you attack, I think. It's not an effect like poison or burn that kicks in at the end of a round IIRC. Are you thinking of the Toxic or Flame Orb hold items that inflict Toxic and Burn on you maybe?

So you're getting both the Life Orb boost and the sheer force boost from cancelling the life orb? That seems terribly broken. If Flare Blitz's recoil is cancelled too, Scarf Darmanitan would be unstoppable.
*Looks it up*
Oh, so Life Orb's recoil will be cancelled if the move you use activates Sheer Force. Well, I guess that would come in handy with rock slide (especially in VGC).
