So maybe the player switched to the putter before getting the reading of 100 yards?
(On the other hand, there are often slight discrepancies between the lie in the picture and the lie that the game tells us the ball is in. So far as I know, the stated lie always prevails over the apparent lie.)
Yes, I suppose he switched by himself.
As for the lie, IMO the ball picture in the lower right corner shows the stated lie - fairway!
I went there and had a look, and the fairway goes close to the green.
