I found original example somewhat artifical, but after thinking on that
I guess that the need for rebase onto master~1 might happen when the last
commit in master is for example to be amended or rebased. 

The "transplanting branch" example feels like more natural to me.

Perhaps adding why one might want to transplant topic branch from one
development branch to other: for example when feature being developed
on topic branch relied on functionality which was at the time topic branch
was started available only in 'next' branch, but meanwhile it matured and
was merged into 'master' (more stable) branch. One would want to base
topic branches on 'master' branch if possible.

This example is from latest post by Andy Parkins, which asked how to
do that. But I find your example as being better, because it shows
even more power of core git history manipulation.

Here I find lack of --interactive option to at least git-am based
rebase; git-rebase could simply pass --interactive option to git-am.
