If you want the "whole" set of changes from inward to appear in outward as a /single/ commit with an appropriate commit message, probably you want to use also the --squash option of git merge.
Otherwise, git will preserve the "structuring" of the history in many commits. This means that:
- if outward does not need any real merge (because it only needs to be advanced to a newer status and not to join some changes of its own with changes from inward), git merge will make a "fast-forward". In other words, you will see outward becoming up to date without the need of any merge-commit at all. BTW that is why --no-commit appears to have no effect in this case: there wouldn't be any merge commit in any case.
- if outward needs a real merge, then git merge will set up everything up to the point of making the merge commit. Then, depending on the presence of the --no-commit option it will or will not make the actual commit.
