Here is the math, if he has 10% lifesteal and has 25 damage from enrage, 55 from base damage and 3.2 from level 1 bonus he would have 83.2 damage, if he did 83.2 damage to enemy 10% lifesteal would heal him for 8.3, that could be achieved on level 1 if you attack low armor target while having armor penetration runes that exceed your target's armor. Since you can have 31 armor penetration maximum, any enemy that has lower than 31 armor would cost you no health to attack him. If that enemy has more armor you will heal less and less, more armor enemy has, less lifesteal for you.

This is not that usefull in lane, but it is very, very useful in jungle, you will be able to start with huge damage at no health cost at all.
