This was previously reported[1]. Based upon a quick scan of that old email thread, I'm not sure we ever came to a final conclusion about whether Git could address this case itself[2] without breaking existing workflows or if it should be the hook's responsibility[3]. Perhaps try having your hook script unset environment variables as explained in [3], or at minimum unset GIT_INDEX_FILE. Also, perhaps this advice[4] applies and you can take a simpler, less heavyweight approach to whatever your hook is doing.
