Basically, the splash and the true damage are two seperate effects, both prompted by the same trigger (an auto-attack). The true-damage is a side effect of auto-attacking, just as the splash is a side-effect of auto-attacking. Neither the true damage nor the splash are attributes of the attack itself, just secondary effects triggered by it.
