Before this patch, makepkg does not check if $dir is a local clone of the right repo. For example, git fetch would be run even if $dir is not a local bare clone of a git repo in present in source(), but a subdir of a checked-out one. That means makepkg can potentially fetch from a completely unrelated remote and update completely unrelated dirs/files. This patch adds a check to make sure we are fetching from the right remote.
