Yep.

The question: Does git-upload-pack which gets it's list of objects with "git-rev-list --objects needed1 needed2 needed3 ^has1 ^has2 ^has3" get any history beyond the top of tree of each branch.

As I read the code it does not.

If the code does not get the history I see some problems. In particular merging with a branch is hard because we may not pull the common history point.
