I believe you are correct unless you check out to a branch named after
the tag? I don't believe it will actually store the tag as part of its
checkout.

Ie:

git checkout <tag>

may show "checked out at <tag>" via status, but that is only because
status uses describe to find that out..

I don't believe we store the information. You could recover it if you
know something about the format so as to distinquish them, ie: if you
only cared about annotated tags vs lightweight tags, for example.
