I'm not clear on what makes "B" more special than "A" in the graph
above. But assuming you know A, don't you just want:

  git log --no-merges topic ^upstream ^A

? That is, "everything in topic, but not in upstream, nor in the parent
of A". Or if you know A and not B, you can use "^B^!" (which means "do
not include commits that are in any parent of B").
