I mentioned in posts No's 7 & 9 that it appears to be an approach to a precautionary landing at a suitable open space.
I'm with you, John - if the aircraft has been displaying symptoms of a possible problem (not sure if this was the case but likely from what has been previously said) then I'd go for a power terminated auto profile to a suitable open space, room and situation permitting.
Obviously might not be doable all the time, and WIRES may well be a factor if you don't have time to check properly, but all things being equal it's going to give you auto potential all the way down if power or drive are lost.
