Think of it not as changing the past, as no actions being changed could've results in Snow being older than Regina. Think of it more as a role reversal, something which doesnt break the laws of magic.

I also dont think the Author can kill anyone by writing the new past, thus explaining Henry, and Emma's existences.

The Author also can't bring back the dead.

And if you look carefully you'll see that he hasn't made anyone new fall in love.
