There's no specific mention of it in the Q&A anywhere, but that's because its painfully obvious. We already know the soul is not on the field, because of things like Great Fate specifying that it nullifies cards in the soul, and that a Q&A mentions that Artiliger only nullified abilities that Dragonarms give to a Neodragon, and not the actual Dragonarms abilities.

And since we know monsters on the field are obviously ON THE FIELD, when a monster on the field becomes a card in the soul, it thus leaves the field, and thus Lifelink activates.

Not that complicated.
