Hi Erik,

The --fork-point option does this:
> Use reflog to find a better common ancestor between <upstream> and <branch> when calculating which commits have been introduced by <branch>.
Since the parent of a is still in the reflog of origin/a, it is not
being rebased (the rationale being that the commit *was* in origin/a
at some point). If you want to disable this behavior, add
--no-fork-point option:
git rebase -ir --no-fork-point
Since this is the documented behavior, it probably is not a bug.
Best,
Cem
