In order for it to create a problem, commits on a branch would have to
be rebased. Because at that point of time, commit author+commit date no
longer uniquely identify a commit.
Rebasing again loses the information you use for identifying a commit.
This may or may be another problem. But the problem of
commitdate+committer not providing uniqie identification for any commit
in a rebased branch is a separate one.
