It procs lifesteal because game mechanics say "I've always been here, and i've always been this way."

Copied from my reply to a similar post on Ability Details page: Vi's W does between 6% and 10% max hp as physical damage every 3rd hit and needs to be ranked up.

Jarvan's Innate does between 6% and 10% max hp as physical damage on the first hit every 6 seconds and doesn't need skill points to rank up.

Vayne's W does between 4% and 8% of max hp as true damage every 3rd hit.

Differences?
 * 1) Jarvan's doesn't have to be ranked up.
 * 2) Vayne's does true damage even if at a lower percentage it completely ignores armor.

Similarities?
 * 1) All three trigger lifesteal.
