Your changeset are not considered as part of the "default" branch while 
there topic is active. The "default" keyword resolve to the head of the 
un-topiced changeset on default. This was an important update in topic 
behavior we made a while back, otherwise when multiple people work in 
topics, the head of branch does not means anything and keep jumping from 
one changeset to another.

If you actually want to jump on "the latest changeset whose branch is 
`foo`", use `hg update 'branch("foo")'`. I am curious of why you would 
want that though.
