What is meant by "her other hand" in the Hadith regarding the washing of Umm Al-Mu'minin Aisha -may Allah be pleased with her- narrated in Sahih Al-Bukhari: "and with her other hand on her left side"?

The text of the Hadith from A'isha (may Allah be pleased with her) states that when they (the women) were in a state of major ritual impurity (janaba), one of them would take water with both hands three times over her head, then with one hand over her right side, and with the other hand over her left side.

What appears evident is that the hand intended for the right side is the right hand, and for the left side is the left hand.
