What is the correct position for a woman to stand in congregational prayer with a single man at home?

If a man leads a single woman in prayer as an imam, she stands behind him, distanced from him, and not to his right or left. The proof for this is the action of the Prophet, peace and blessings be upon him, in the hadith narrated by Anas: "So I and the orphan stood behind him, and the old woman stood behind us." This also indicates that a woman stands behind men, and if there is no other woman with her, she stands alone behind him.
