'Hand off' is a minefield. In Br Eng sports (especially rugby), handing off someone is keeping them at arm's length and/or pushing them away. I came to realize when I was working for a US firm that a 'hand off' was a quite constructive thing (and not a a mixture of aggression and defence).
We would call what Horsley did handing over; what his superiors did was to hand/pass the list on.
