How do you know she's moved out? Meaning has she told you, or do you see no activity around the place. I don't interpret that as you can't be there until Day 51. Once she leaves, she makes redundant the concept of exclusive use and possession, since she's no longer using the property. But if she wants to be a Hole, she might cause a problem...so it goes to your evidence that she's finished moving out.
