I do not quite get this part (note that it is impolite to ask people
to go to stackoverflow or any external site to answer questions
asked here, but I am making an exception today):

  $ git log --oneline --graph origin/master origin/topic1

  It will show all branches anyway, even though I've specified I only
  want to see two of them.

These should show commits reachable from these two branches,
origin/master and origin/topic1, and nothing else.

  $ git log --oneline --graph \
    origin/master origin/topic1 \
    --not $(git merge-base --all origin/master origin/topic1)

would stop where the histories of these two branches meet (assuming
that you consider that the common ancestors of these two not
interesting when you say "all branches anyway", but these common
ancestors are still part of these two branches ;-).
