It helps detecting supply chain attacks. The "make dist" archive is
basically impossible to reproduce, so we need to trust the uploader that it
was not modified. For the git tarball, all changes are visible in the
commit history. While someone still needs to look, it's much easier to spot
something.
And that is not theoretical: The xz backdoor did just that with a modified
build-to-host.m4.

I'm not sure what you mean with that.
