At 20 life

They lose 10 life.

I don't think so, the life total is SET to 10. There is no gain or loss of life

If a life total is changed they lose or gain life until their life total becomes the changed number.

this is correct. from the gatherer:
For a player's life total to become 10, what actually happens is that the player gains or loses the appropriate amount of life. For example, if the targeted opponent's life total is 4 when this ability resolves, it will cause that player to gain 6 life; alternately, if the targeted player's life total is 17 when this ability resolves, it will cause that player to lose 7 life. Other cards that interact with life gain or life loss will interact with this effect accordingly.
