It's not the armour pen that makes the item statistically significant for him; it's the CDR. His true damage % of his total damage against champions is also one of the highest in the game - especially if you put early points into it - making the penetration really unappealing. if you're worried about the value you're getting from your lifesteal, get armour and MR.
